Abstract
In most of the industrial application including power plants, chemical, refrigerator and air conditioning systems use heat exchangers is most common. Heat exchangers have several industrial and engineering applications.In recent years, the high cost of energy and material has resulted in an increased effort aimed at producing more efficient heat exchange equipment.The usual goals are to reduce the size of a heat exchanger required for a specified heat duty, to upgrade the capacity of an existing heat exchanger, to reduce the approach temperature difference of the fluids, or to reduce the pumping power.The study of improved heat transfer performance is referred to as heat transfer augmentation, enhancement, or intensification. Heat transfer augmentation techniques refer to different methods used to increase rate of heat transfer without affecting much overall performance of the system.Active and passive cooling are the two possible methods for removing heat. In the past decade, several studies on the active and passive techniques of heat transfer augmentation have been reported. The present paper is a review on progress with the active and passive augmentation techniques in the recent past and will be useful to designers implementing these augmentation techniques in heat exchange
