- The lectures were interesting but when looking at the slides they were mainly entirely composed of pictures which was not useful at all when revising. The book was interesting but lacked criticial information which had to be found through other sources (google) Felt underprepared for the exam questions when taking into account the lecture notes. » (Some extent)
- The Power Point printouts were sort of useless for the preperation of the exam. Some good lecture notes would be good,.» (Some extent)
- If we are suppose to be able to do the dicretisatiopn asked on the exam we need more about that beacuse this was just unfair to have as an exam question.» (Large extent)
- I think the Barnard book gave a good understanding for the basics of Road Vehicle Aerodynamic. This will help when learning more advanced stuff.» (Large extent)

- Racing car improving was impossible. No time to do it properly. No time enough at the wind tunnel.» (Adequate)
- My problem: Now I know what exists on a car in order to have some Aerodynamic optimizattion. BUT I dont know how to optimize one. Its nice how to stick some addition to a truck but I still dont know how to optimize the general form (the iterating process)» (Adequate)
- Good course but I had higher expectations, could be even more focus on understanding results from cfd or windtunnels.» (Good)
- There could be additional assignments. Work load is very less» (Good)
- The course and lectures were very interesting and I come away with a greater appreciation of aerodynamics but I don"t feel I"ve learned how to actually design a car appropriately regarding its aerodynamics. » (Good)
- RVAD was a fun course and not only that I can"t think of a single time when something was unclear. The administration and layout of the course was flawless. Good teachers and assistants.» (Excellent)

- sometimes too much talk about famous people.» (Adequate)
- Too much fancy cars.» (Adequate)

- It was to much focus on theory compared with the rest of the course. The dircretization of the heat transfer is/and should not be a part of the course! There are other courses where this is a part of the course. Would be better to discuss how cfd results should be interpreted» (Fair)
- Good intention with showing the theory behind but maybe it was a bit too deep?» (Fair)
- The material was interesting but I think too much time was spent on the mathematical derivation at the end. » (Adequate)

- I did not attend, as I had to go when the session started.» (?)
- There was no theory in the book to understand it. There should be some literture hand out of the thoery to understand all questions. But the question that also was on the exam was excellent for understanding!» (Adequate)
- Interesting questions but the mathematical ones seem a little irrelevant since they were not tested in the exam. » (Good)

- Didnt really feel connected to the course...» (Poor)
- not a good solution to sit in these classrooms and try to calculate things. ML1-4 would have been better.» (Fair)
- Should be earlier in the course like week 2,3,4 and 5.» (Good)
- Unfortunately a very bad lecture room for exercise...» (Good)
- Maybe giving the exercises before the session would be better for studying them deeper.» (Good)
- More of them.» (Good)
- One stiupid thing occured. The ground flow exercice took place before the lecture and the PhD students didnt want to answer the questions and since I dont know anything before the lecture about that topic it was unneccesary complicated.» (Good)

- The report and pressentation should have been friday study week 6 not the day before the exam...» (Good)
- Good fun to carry out project but having the project presentation and the lab the day before the exam was less than ideal for preparation. » (Good)
- Deadline to late.» (Good)
- good, except for the date of the presentation. It was to close to the exam.» (Good)

- 2 hours in a row are not enough. More time to think about changes is necessary.» (Fair)
- (Good)
- Could have given more time» (Good)

24. What should definitely be preserved to next year?

- Wind tunnel session. »
- Paraview, all lectures.»
- Lab works, presentations.»
- the project, lectures»
- In my opinion the course is really a fantastic one. I would suggest to keep most part»
- The project and Tim Walkers lecture»
- Wind tunnel lab, ParaView post processing, VCC wind tunnel visit»
- Inspirational lectures containing interesting history and facts about sport cars. »
- The course as it was this year»
- Lab work, Volvo wind tunnel visit and guest lecture.»
- I think the course should stay as it was this year.»
- The Projects,Exercises.»
- Guest lecture»
- Wind tunnel testing! The visit to Volvo"s wind tunnel. »
- Windtunnel experiment»
- Wind Tunnel project.»
- Everything»
- The project and paraview should be preserved»
- Wind tunnel laboratory.»
- the guest lectures.»
- wind tunnel project»
- Everything»
- The windtunnel lab.»

25. What should definitely be changed to next year?

- More in-depth explaining of the theory (e.g. Navier-Stokes). »
- Exam question policy - more fair.»
- exercise»
- 1) The excercises should be ealier in the course. 2) There should not be the heat transfer caluculations that where in the exam. 3) The project should be handed in one week ealier»
- Later examination date. It was very stressful to have presentations for 4 hours the day before the exam. »
- Work load. There could be an additional assignment.»
- nothing to add.»
- The level of the course needs to be higher. As it is now it"s just ridicules and pointless. It should be either more fluid mechanics or CFD. »
- Cant find something to fault.»
- Detailed basics of applied fluid mechanics session.»
- CFD»
- The report and presentation could maybe be at the start of the last week. The lecture notes should definitely contain more writing and information instead of just pictures. The second half of the CFD presentation should be changed. »
- There should be more calculations»
- Maybe a lecture on the basics or a handout treating this basics of fluid mechanics on the webpage.»
- Should atleast teach two-D simulation of CFD(ex- aerofoil). Not just the post processing, but everything before that. Paraview does look good, but being a master student, it seems less competitive.»
- The time between presentation and exam should be changed , presentation should be kept at least 2 days before the final exam.»
- Question 11 on the exam.»
- presentation date.»
- Have some defined basic knowledge required. If you dont have it, dont come to the lecture. Therefore get the basic theory (=bernoulli ect) out. Move more theory of CFD inside.»
- CFD classes should be improved»
- More wind tunnel time and a bit of CFD work. »
- More theory about the airflow.»

26. Additional comments

- Lennart is a wonderful professor, I wasn"t that interested in RVAD before attending the course, but he definitely made me (us?) love this field.»
- Question 11. on the exam related to theoretical calculations regarding CFD should have not been included in the exam since this material was not focal and it was not covered in the given exercises during the course. I consider this unfair.»
- Regarding the excercises if you provide us with some material (ie. formulas or support materials) that would be useful. Overall opinion it is one of the best couse in Chalmers.»
- Thanks for a great course! Learnt a lot and it was very interesting. Has really opened my eyes for RVAD.»
- Overall very good. I for one learned alot about RVAD and is pleased that the focus on the course was on the basic behaviour of the airflow and not on formulas and equations. »
- A very good course, overall.»
- This is probably the most insubstantial course I"ve ever read during my time on Chalmers.»
- Enjoyed the module, favourite so far at chalmers, so congrats to all involved»
- Very good course !!!»
- n/a»
- More time would be nice for the wind tunnel laboratory work.»
- Nice but too applied content»
- More wind tunnel time and a bit of CFD work. »
- I think it was unfair to have a question on the exam which only had been done on a lecture. There were no exercise or anything to study how to do the calculation.»
