Thermophysical Analysis of Microconfined Turbulent Flow Regimes at Supercritical Fluid Conditions in Heat Transfer Applications

Wall-to-fluid Heat Transfer in a Catalytic Reactor at Supercritical Conditions

Computational fluid dynamics (CFD) studies can be used for improving the understanding of fluid flow and heat transfer in packed bed systems. The objective of this work was to study the heat effects in packed bed reactor under supercritical conditions using CFD comparing the simulations with empirical correlations. Simulations were done for a geometrical model of packed bed of cylindrical catal...

Diameter effect on the heat transfer of supercritical hydrocarbon fuel in horizontal tubes under turbulent conditions

This article presented a numerical investigation of supercritical heat transfer of hydrocarbon fuel in a series of horizontal tubes with different diameters. It has been carried out by solving Reynolds averaging equations of mass, momentum and energy with the LS low-Reynolds number turbulence model using the pressure-based segregated solver based on the finite volume method. For the purpose of ...

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer

The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
