CFD Modeling of Flow and Heat Transfer Processes in a Cooler for Sampling from an Airlift Fermenter

The article deals with CFD modeling of fluid flow in a cooler designed for sampling from an airlift fermenter. The authors focused on the hydraulic and thermal analysis of a tube-in-tube cooler. Boundary conditions and fluid parameters were determined based on experimental measurements provided by the client and the av...

Simulation of Thermo-Hydraulic Performance of Solar Air Heater with Longitudinal Baffles

This research offers a 3D analysis of a solar air heater’s performance using Computational Fluid Dynamics (CFD) and COMSOL Multiphysics software. The air heater design is multi-pass and therefore, the air will remain in the heater longer, thus increasing the transfer of heat from the surface to the air. Fluid flow and...

Thermo-Fluid Analysis of a Single Slope Water Distillation Unit using Numerical Approach

A numerical study has been performed using COMSOL Multiphysics to investigate the interactions between heat transfer (HT) and fluid (FL) during solar desalination via a single-slope solar still. The model consisted of a shallow saline basin, a black absorbing plate, insulated walls, and an inclined glass cover that was...

Effect of bubble motion on local heat transfer around a tube across horizontal in-line and staggered tube bundles in bubbly and intermittent flows

Cross-flow boiling in horizontal tube bundles occurs in kettle type evaporators. Convective heat transfer due to the motion of vapor bubbles is an important factor for boiling heat transfer in the evaporator under low heat flux conditions. To clarify the liquid agitation effect on heat transfer, the local heat transfer...

Thermal-hydraulic performance of coolants flowing in channels with varied cross-sections and flow path geometries: A numerical study

Heat transfer and hydrodynamic characteristics are compared numerically for the straight, stepped, zigzag spiral and Archimedean helical tubes of various cross-sectional shapes under laminar flow conditions ranging between 1300 - 2500 of water and CuO-water nanofluid. The channel geometries considered are circular, squ...

Experimental and Numerical Analysis of Heat Transfer Enhancement Using Nanofluids in Circular Pipes

This study investigated heat transfer enhancement in circular pipes using nanofluids through a combined experimental and numerical approach with the aim of improving the thermal performance of conventional heat transfer fluids. The motivation for the study arises from the limited thermal conductivity of traditional...
