A.R.A.P.'s Second-Order Closure Model: Comparison with a Number of Complex Turbulent Flows.

Abstract

The flows computed by A.R.A.P. for the AFSOR-HTTM-Stanford Conference on Complex Turbulent Flows are reviewed and discussed. Eighteen different flows were simulated using A.R.A.P.'s full Reynolds stress model. These flows ranged in complexity from simple homogeneous decay to fully elliptic, unsteady flows behind a backward facing step. The results are generally quite good, demonstrating that a wide range of problems can be handled by Reynolds stress closure models. However, there are some notable exceptions. The probable reasons for the discrepancies are indicated and directions for model improvements are suggested. (Author)
