Here we investigate the irreversibility aspects in magnetohydrodynamics flow of viscous
nanofluid by a variable thicked surface. Viscous dissipation, Joule heating and heat …

Forced convective turbulent hydrothermal analysis in a double pipe heat exchanger is
presented experimentally. Perforated turbulators have been utilized in annulus region. Hot …

Abstract Ground-Coupled Heat Pumps (GCHPs) are regarded as an effective technology for
building energy development and residential hot water production. The essential challenges …

A novel twisted annulus between two counter-twisted oval tubes is proposed for a double-
tube heat exchanger. The oval tubes of the annuli have same twist pitch, but twist with …

In this paper, the design and thermo-hydraulic performance of a double pipe heat exchanger
with helical baffles in the annulus side, are investigated numerically. Three-dimensional …
