Experimental study of parameters of surfaces coated with regular relief
Engineering Education # 01, January 2013 DOI: 10.7463/0113.0532996 This article presents an analysis of published data on numerical and physical (experimental) study of thermal-hydraulic characteristics of different methods of heat exchange vortical enhancement. It is shown that the most effective is the use of heat exchange surfaces coatedwith regular relief (holes) which have a simple production technology combined with high thermal-hydraulic characteristics. The authors present a modernized test bench that allows, in a single experiment, to determine resistance and heat exchange parameters for two plates which are parallel to each other (smooth plates and plates coated with regular relief). In this case, resistance is determined by "weighing" on tensometric scales, and parameters are determined by a time-dependent heat exchange method using thermal imaging equipment. The authors present data of an experimental study of two types of heating surfaces. It is shown that surfaces with oval holes have a large (20-35%) resistance than surfaces with hemispherical holes.
