Abstract
Energy crises are one of the increasing problems in industrial engineering. Thermal system is a major part of energy consumption. Therefor it is necessary to increase efficiency of the thermal systems. Heat exchangers are widely used in petrochemical, pharmaceutical, chemical, power and food industry, heat recovery systems, air–conditioning, refrigeration, central heating systems and cooling automotive components. Hence it is necessary to researchers to focus on to increase the efficiency of the thermal system. The expansion of activities focused on the intensification of heat exchange, reducing the weight and dimensions of heat exchangers, increasing their productivity is needed to decrease energy and material consumption as well as saving the cost of heat exchange equipment. Heat transfer enhancement is majorly depends on heat transfer surface area. Heat transfer surface can be increased by various passive methods. The use of corrugated surface is an effective method of intensification of heat transfer in heat exchangers. Corrugations represent a passive technique. In addition, it provides effective heat transfer enhancement because it combined the features of extended surfaces, turbulators and artificial roughness. In this work the analysis of corrugated profiles and effect of geometrical parameters, operating parameters, insertion of thermal conductive barriers on it was studied.
