Abstract:

Based on ax-symmetric jet and plane jet ,this article stated an inference about air ventjet angle of automobile instrument panel from Prandtl's mixing length hypothesis and the theory of parallel multiplejets, which was confirmed by finite element simulation analysis and tests.The results of the study on vehicle engineering show that increasing the number of vanes doesn't change yet angle.

Key words: vehicle engineering, turbulent jet, vane, air vent, instrument panel, diffusion angle
