Calculation

STARCS has a long tradition of combining calculations and tests for optimum results.

Calculation

Calculations are a vital part of most types of technical evaluation, so also for evaluation of aerodynamic problems. Not all problems need wind tunnel testing or CFD analysis (Computational Fluid Dynamics).
An analytical desktop study using pure experience and handbook rules can be a very sophisticated tool for some problems.
 

Validation

Wind tunnel test are a vital tool in developing and validating CFD codes and methods. By the use of advanced measuring technique, vast amounts of detailed data of the flow field around the test object
can be attained in the wind tunnel. The pictures to the right are an example of how information from wind tunnel testing, here attained and visualized by PIV, can be used for validation of CFD methods.

 Calculations as a complement to testing

The use of calculations as a complement to wind tunnel tests offers the possibility to study details of the flow around a test object in the tunnel that are not otherwise easily available.
 
The pictures below represent an example from STARCS of the use calculations in combination with wind
tunnel testing. It was an accident investigation (report in Swedish) performed for the Swedish Accident Investigation Board of the effect of a buss passing a truck with trailer.
 
The calculation was validated against a previous wind tunnel study conducted in STARCS' low speed wind tunnel LT1.
