Thermohydraulic performance optimization of a novel double-pass solar air heater with vertical PCM-integrated cylinders: A comparative study

Case Studies in Thermal Engineering
Solar air heater (SAH) systems are efficient devices to capture solar energy, but their consistent thermohydraulic performance is limited by poor convective heat transfer and fluctuating solar energy.

Helical Baffle Thermohydraulic Performance Versus Segmental Baffle One

Mechanics, 2022
In this contribution, we reworked the Bell-Delaware technique for a HB-STHX to systematically study its thermohydraulic performance behavior in the shell side. The helical baffles are continuous quadrant sectors with five inclination angles 25°, 30°, 35°, 40° and 45° and are exanimated for six different values of Reynolds number  from  up to 40 .

A Review of Airside Heat Transfer Augmentation with Vortex Generators on Heat Transfer Surface

Energies, 2018
Heat exchanger performance can be improved via the introduction of vortex generators to the airside surface, based on the mechanism that the generated longitudinal vortices can disrupt the boundary layer growth, increase the turbulence intensity and ...
