Air Flow Interference Effect in the Building Models
Abstract
The paper presents results of oil-black visualization of air flow separated by the groups of three building models designed to simulate buildings mutually affecting each other. The air flow behavior is described depending on the building models positions. Experiments are carried out at 7×104 Reynolds number, 0 and 45° angles of attack at a fixed height of the building models. The aim of this work is to determine the correlation between air flow around the models and the distribution of the local heat transfer and pressure factors obtained during the experiments in a wing tunnel. Also, the assessment is given to the hydrodynamic structure of separated flows, their behavior and amount.
