Experimental Evaluation of Thermohydraulic Performance of Tubular Solar Air Heater

International Journal of Renewable Energy Development, 2022
The thermohydraulic performance of a new design solar air heater (SAH) design was examined experimentally in this paper as a trial to improve the flat-plate SAH’s efficiency. A flat-plate solar air heater (FPSAH) and a jacketed tubular solar air heater (JTSAH) having similar dimensions were constructed to compare their thermal performance efficiencies.

Heat Transfer Enhancement in a Three‐Fluid Tubular Heat Exchanger Using Al2O3–Water Nanofluid

Engineering Reports, Volume 8, Issue 7, July 2026.
Experimental investigation of Al2O3‐water nanofluid in a three‐fluid tubular heat exchanger shows enhanced Nusselt number with increased flow rate and nanoparticle concentration, while the friction factor reduces. Thermal performance factor exceeds unity, confirming the net benefit of nanofluid use in multi‐stream heat exchangers.

A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

Environmental Progress &Sustainable Energy, Volume 45, Issue 4, July/August 2026.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.

Effective Efficiency of Solar Air Heaters of Different Types of Roughness Geometries over Absorber Plate

Walailak Journal of Science and Technology, 2014
Artificial roughness has been found to enhance the rate of heat transfer in solar air heater ducts. However, improvement in heat transfer enhancement is invariably accompanied by increased pumping power. Several investigators have investigated the effect

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 .

Experimental Study on the Thermohydraulic Performance of Oil-Cooled Heat Sinks for Power Electronics

2022 28th International Workshop on Thermal Investigations of ICs and Systems (THERMINIC), 2022
Using the lubrication oil in (hybrid) electric vehicles as both coolant and lubricant, thereby eliminating the need of a separate coolant circuit, can improve the overall efficiency of the cars. However, oil exhibits inferior heat transfer properties compared to conventional coolants (mainly higher viscosity, lower thermal conductivity and lower ...
