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 …

Numerical Study on Thermal Performance Assessment of a Compact Heat Exchanger Equipped with Two Broken Twisted StripsBy Suvanjan Bhattacharyya, Himadri Chattopadhyay, Sarbojit Bhattacharjee, Niladri Ghosh, Soutik Sarkar
Abstract: Twisted strips are a widely used technique for heat transfer enhancement. In the present study, it proposed that two broken twisted strips aiming at achieving good thermohydraulic performance. Effects of the two broken twisted strips (BTS) on the heat transfer, friction factor and thermal performance factor behaviours in a heat exchanger are reported along with smooth duct. The computations are based on the finite volume method with the SIMPLE algorithm …
