TRANSITION CLOSURE-MODEL FOR PREDICTING TRANSITION ONSET

A unified approach that makes it possible to determine the extent and onset of transition in one calculation is presented. It treats the non turbulent fluctuations in a manner similar to that used in describing turbulence, As a result, the complete flowfield can be calculated usin g existing computational fluid dynamics codes and without the use of s tability codes. The method is validated by comparing the results for f lat plates, airfoils, and infinite swept wings with available experime nts. In general, good agreement is indicated.
