Abstract
An experimental setup designed to study the processes of unsteady heat exchange in the interaction of a pulsating turbulent heated-air jet with a model object, which is placed in a stationary drifting flow of cold air, was developed. In fact, this is the interaction of a vertical heated jet with a transverse drifting “cold” stream, during which an object is periodically heated and cooled at a given pulsation frequency of the jet. The design of the setup and its main element, a device for creating a pulsating jet, are described in detail. The characteristics of the pulsating heated jet and the drifting flow in the working region of the setup are given. As an example, the results of nonstationary heating of the plate of a pyroelectric transducer by a pulsating heated jet and subsequent cooling when interrupting the flow of the warm gas are presented.
