In this paper, after a short review of the heat exchangers (HEX) types and applications with
different technologies was presented, a lot of parameters which mainly affect the thermal …

This study proposes a systematic methodology for improving PEMFC's performance
combining computational fluid dynamic (CFD), artificial neural network (ANN), and intelligent …

Based on topology optimization, two novel strip fins used in the fin-and-tube heat exchanger
are proposed, and an alternative interpolation approach is used. Reynolds number and heat …

The isentropic efficiency of vortex pump in Organic Rankine Cycle (ORC) system has an
important influence on the performance of the system. In this paper, vortex pump …

Heat transfer and fluid flow in the offset strip-fin heat exchanger are studied numerically, fin
by fin. The impact of the offset strip-fin geometry on j/f performance is also evaluated. The …

The aim of this work is to analyze different tube-side inlet boundary conditions in order to
properly model heat transfer mechanism in a crossflow air-to-water fin-and-tube heat …

The operating performance of the expander, as the core component of the ORC system,
directly determines the comprehensive performance of the system. Single screw expander …

Without defects inherent in conventional welded finned tubes, nonwelded integrally-molded
spiral finned (IMSF) tubes proposed here have “zero” contact thermal resistance and high …

With the increasing requirement for environmental protection in the area of ship rust
removal, ultra-high-pressure (UHP) water-jet technique attaches much attention. Because …

The present work aims at optimizing the geometry of curved trapezoidal winglets to enhance
heat transfer rates (expressed as Colburn factor, j) and minimize pressure losses (expressed …
