Abstract

Highlights: Non-contact laser holographic interference technology. Application of micro-fluidic wind tracer visualization. Influence of space heat source group on flow and heat transfer. Describe the change of temperature field and flow field under various conditions in the experiment. Abstract: There have been many simulation studies on the natural convection heat transfer of closed chambers. This paper mainly explains the experimental research and discusses the experimental principle, steps and error analysis. Analyze the influence of the number and spacing of heat sources on the flow and heat transfer in the cavity. The experimental methods used are holographic interference technology and smoke wind tracing technology.
