Hydraulic and Thermal Performances of a Counter-Flow Heat Exchanger with FinsBy Anirban Roy, Suvanjan Bhattacharyya, Niladri Ghosh, Indraneel Roy Chowdhury, Sudipta Sarkar
Abstract: Computational analysis has been conducted to examine the flow and heat transfer characteristics in a two-dimensional iso-thermal-fluxed circular-duct fitted with fins. The computations are based on finite volume methods employed with the simple algorithm. Paper reports are based on the computational fluid dynamics (CFD) modelling studies on laminar flow heat transfer, friction factor and thermal performance of a counter-flow heat exchanger equipped with two types of tube insert, one including …

Application of a Centralized Solar Powered Air-conditioning System for an Engineering College Building in Kolkata RegionBy Rajat Subhra Bhowmik, Suvanjan Bhattacharyya, Kanchan Kumar Das
Abstract: Adaptive cooling technique has been proposed as an energy efficient strategy for a centralized HVAC system in summer environment. Energy consumption is basically defined as an effort to minimize unnecessary energy consumption as by-product of the required energy consumption or to minimize the gap between required energy consumption and final energy consumption. There is a developing, state government trend of installing renewable energy in Kolkata. One area of interest is …
