In the present work, thermo-fluidic behavior of a heat exchanger tube with conical shaped insert has been investigated help finite volume method. To enhance transfer rate, two different types roughness used in i.e. protrusion and dimple roughness. A three-dimensional computational model RNG turbulence is for simulation it performed three diameters (3 mm, 6 mm 9 mm) pitch space (120 180 both The...

The aim of this article is to investigate the effect mass and heat transfer on unsteady squeeze flow viscous fluid under influence variable magnetic field. observed in a rotating channel. equations momentum conservation are coupled with field energy equations. By using some appropriate similarity transformations, partial differential obtained then converted into system ordinary solved by Homoto...

This study investigates a three-dimensional elliptical microchannel heat sink for dissipation in laminar forced convection. The seeks to improve thermal performance and overcome overheating associated with excessive temperature commonly experienced heat-generating equipment, which is beyond the usually specified by manufacturer. objective of evaluate transfer, fluid flow, entropy generation cha...

In recent years, there has been an increasing interest in heat transfer enhancement using nanofluids channels due to current devices become smaller and more compact are expected perform better. Thus, we attempt introduce hybrid flow a straight pipe Ansys Fluent software. The simulation was prepared with certain specific parameters such as the hydraulic diameter is set at 10mm, continuum, Reynol...

The present work is devoted to the assessment of a low-noise turbulence generation methodology used produce boundary layer with three-dimensional resolved at exit jet nozzle reproduce experimental conditions. method relies on use roughness elements introduced in computational domain Immersed Boundary Conditions and ZDES mode 3 (Wall Modelled LES branch ZDES). simulation round M = 0.9 Reynold nu...

In this article, numerical simulation is performed for mixed convection lid-driven flow of CuO -water nanofluid enclosed in a curved corrugated. Cylindrical obstacles having three different constraints: (adiabatic, cold, and heated) at its surface are considered. Internal heat generation/absorption uniform provided the vertical wall cavity. The bottom insulated, curve surfaces maintained with c...

ω(t, x) ∈ Rand b(t, x) ∈ R, and p(t, x) ∈ R denote, respectively, the microrotational velocity, the magnetic field, and the hydrostatic pressure. μ, χ, κ, γ, and ] are positive numbers associated with properties of the material: μ is the kinematic viscosity, χ is the vortex viscosity, κ and γ are spin viscosities, and 1/] is the magnetic Reynold. u 0 , ω 0 , and b 0 are initial data for the vel...
