The helical coil heat exchanger (HCHX) is one of the most popular heat transfer devices in
heat pump water heaters. In this study, the Computational Fluid Dynamics (CFD) software …

In order to study the thermal economy of the feed water heater (FWH) start-up process
(SUP), a dynamic mechanism model has been established, and the dynamic exergy …

Earth to air heat exchanger EAHE is a renewable technique based on a geothermal source.
Arid regions are characterised by hard winter and summer weather conditions, which lead to …

A heat dissipation model of discrete elliptical cylinders with heat generation on a thermal
conduction pedestal cooled by forced convection is established. Constructal design is …

In this study, entropy generation in laminar mixed convection in a square fluid-filled cavity is
numerically studied. The middle of the lower wall of the cavity is heated to a constant …

This works presents a second law analysis on a heat exchanger tube configurated as
circular smoot tube (CST), elliptical smooth tube (EST) and elliptical twisted tube (ETT) with …

A dynamic simulation model has been established to study the entropy characteristics of the
feed water heater start-up process, and the dynamic entropy analysis was conducted. The …
