A Review Paper on CFD Simulation of Square Threaded & Helical Twisted Pin Fin Arrays in a Rectangular Channel to Enhance Heat Transfer

The present paper gives the review on CFD Simulation of Square Threaded & Helical twisted pin fin arrays in a rectangular Channel to enhance Heat transfer. The variable parameters are arrangement and variable geometry (Square Threaded & Helical twisted pin fin arrays) of pin fin arrays by using the transient single blow technique. The experiment covers the following range Reynolds number 13, 50042, 000, the clearance ratio (C/H) 0, 0.33 and 1, the inter-fin spacing ratio (Sy/D) 1.208, 1.524, 1.944 and 3.417. Correlations equations are develop for enchantment of thermal efficiency of three dimensional fluid flow. The experimental review shows that the modifications with inline and staggered arrangement and different geometries ( Square Threaded & Helical twisted pin fin arrays) may lead to heat transfer enhancement by increasing thermal efficiency. Nusselt number and Reynolds number are considered as performance parameters for the experiments. The thermal performance analysis is made under constant pumping power constraints. For higher thermal performance lower inter-fin distance ratio and clearance ratio and comparatively lower Reynolds number should be preferred for staggered arrangement and different geometry. The result of staggered configuration and different geometries are also compared with the result of inline arrangement and pin fins with cylindrical geometry.
