    Abstract :

    After tubular heat exchangers, Plate-fin heat exchangers (PFHEs), are the most common types of heat exchangers in thermal engineering applications. Plate fin heat exchangers, because of their low weight, compactness and high effectiveness are widely used in cryogenic and aerospace applications. This paper focuses on the passive augmentation techniques in the recent past and will be helpful to designers implementing passive augmentation techniques in heat exchange instruments. For the compensation of the poor heat transfer properties, the surface area density of plate heat exchangers can be increased by making use of the secondary fins such as, triangular fins, off-set fins, wavy fins, louvered fins etc. In addition, for the enhancement of heat transfer a promising technique is the use of longitudinal vortex generators. Due to the pressure difference generated between the front and back surface of the vortex generator produces the longitudinal vortices. These longitudinal vortices facil
