In this study, the effect of both cylindrical grooved pin-fins (C-GPFs) and triangular grooved pin-fins (T-GPFs) into the rectangular channel on heat transfer augmentation, Nusselt number and friction factor were experimentally ...

In this study, heat and fluid flow in a plate-fin heat exchanger with wing-type convergent-divergent longitudinal vortex generators (CDLVGs) were studied experimentally. A cross-flow plate-type heat exchanger was designed ...

An experimental study was conducted to investigate heat transfer and flow characteristics under impingement of a multiple circular jet array with perforated rib surfaces (PRS) and solid rib surfaces (SRS). Heat transfer ...

In this study, to obtain definitive information about the effects of spring-type turbulators located in the inner pipe of a concentric heat exchanger, the rates of exergy transfer Nusselt number (Nue) and exergy loss (E*) ...

Both new punched triangular vortex generators (PTVGs) and punched rectangular vortex generators (PRVGs) have been developed. Both the triangular and rectangular vortex generators were directly punched from the longitudinal ...
