Simulating tornado-like enhancement of heat transfer for low-velocity motion of air in a rectangular channel with cavities. Part 1: Selection and justification of calculation methods

Existing experimental data on the subject are briefly analyzed and the main objectives of calculation studies on the problem area are determined. Details of a calculation procedure are described, the choice of Menter’s shear stress transfer model is substantiated, and results are presented from testing a multiblock approach for numerically simulating hydrodynamics and heat transfer in low-velocity near-wall airflows.
