INTEGRAL HEAT transfer between building models at small distances and different tandem arrangementS
Abstract
The paper presents the pilot study results on the average heat-transfer coefficient for building models arranged on a specialized aerodynamic test bench comprising a subsonic wind tunnel, thermal models and devices for giving thermal boundary conditions, heat sensors and measuring equipment. A change of the average heat-exchange coefficient of the building model located behind another one, is shown depending on the distance between them at a fixed Reynolds number and the airflow angle of attack.
