EFFECT OF THE RAYLEIGH NUMBER ON THE MEAN NUSSELT NUMBER AND THE MEAN TEMPERATURE IN A NATURAL CONVECTION FLOW WITH AN ELLIPTICAL-CYLINDRICAL GEOMETRY

This study presents the results of a numerical simulation of fluid flow within a chamber bounded by a horizontal, flat wall heated at a constant flow rate and an upper wall with an elliptical outline. The results of this simulation enable the implementation of a cooling system utilising natural convection. The key para...

Unsteady Flow Past an Infinite Vertical Cylinder in Rotating Fluid under Influence of Uniform Magnetic Field and Nonlinear Regression Analysis of Nusselt Number

The purpose of this research is the analytical solution of unsteady natural convective flow of a viscous incompressible fluid, which flows over an isothermally heated infinite vertical cylinder. Uniform magnetic field is applied in the direction perpendicular to the cylinder and normal to the direction of the flow. Con...

Numerical simulation of fully developed laminar flow and heat transfer in a circular pipe

This work involves the computational analysis of two-dimensional heat transfer through convection and laminar flow of a fluid. The application was conducted on a circular pipe with fully developed laminar flow, taking into consideration boundary conditions such as the wall’s uniform temperature and constant heat fl...

Turbulent flow in a square duct at extreme Reynolds number

Abstract Content of image described in text. We investigate pressure-driven turbulent flow in a square duct using wall-modelled large-eddy simulations (WMLES) of the Navier–Stokes equations. An equilibrium wall model based on the logarithmic law is employed, yielding results in close agreement with direct numerical sim...

NUMERICAL INVESTIGATION OF THE HYDROTHERMAL PERFORMANCE OF TURBULENT FLOW IN ELLIPTIC-CONICAL TUBES

The need for high thermal performance and compact design of heat exchangers in modern energy and industrial systems is prompting current studies in passive heat transfer enhancement techniques. This study investigated, for the first time, the effect of using elliptic-conical tubes on hydrothermal performance compared w...

Thermal Buoyancy as a Wake Controller: Coupled Wake Dynamics and Heat Transfer in Mixed Convection

The dominance and impact of pronounced thermal buoyancy effects on the thermal and hydrodynamic properties of a horizontally heated cylinder of circular configuration immersed in a vertically ascending laminar flow stream have been numerically investigated. The dynamics are determined by numerically solving the standar...
