Abstract The thermal properties of Octadecane vary due to the addition copper oxide (CuO) nanoparticles. synthesis two nano‐enhanced phase change material (NEPCM) required implementation two‐step method, using as base and CuO nanoparticles at 2.5 5.0 wt%. experimental characterization determined specific heat capacity, conductivity NEPCMs solid phase, including enthalpy temperature. These resul...

Abstract The article presents the results of mathematical modeling in a two-dimensional formulation mixing process by mutual diffusion and separation flows Newtonian fluids microfluidic channel with five outlets. Branches are used to separate into fractions given concentration one components mixture. occurs laminar flow regime, without chemical thermal interaction. mixture model was set up form...

In this study, a 3D Computational Fluid Dynamics (CFD) model was developed to simulate the drying process of maize ears cobs in mixed-mode solar grain dryer. The dryer system is aimed operate under forced convection and integrated with preheater heat air prior entering collector. great accuracy using SolidWorks software CFD simulation carried out ANSYS Fluent software. study at analyzing predic...

The present work is interested in the mathematical and numerical modeling of effects different parameters such as angle cone, length hot source radius, on thermal plume flow interaction with its surrounding. behavior guided can give us more knowledge about control applications relevant to environment industry. This study investigates surrounding environment. To determine that influence this we ...

In order to reveal the influence of air leakage on oxygen concentration in goafs fully mechanized caving mining with a shallow buried and high height, No.122108 working face Caojiatan coal mine different seasons was tested by SF 6 tracer gas test method. Based result test, “three zones” spontaneous combustion goaf were simulated using Ansys Fluent fluid dynamics software, compared that field te...

This paper primarily focuses on the formulation and validation of mathematical numerical models for a new electrolyte-supported solid oxide fuel cell stack. By leveraging modeling, main goal is to deepen understanding operational aspects transport phenomena within this system. The developed are implemented in ANSYS, Inc., Fluent software, which enables range simulations. To validate models, sta...

Air-cooled battery thermal management system (BTMS) is a widely adopted temperature control strategy for lithium-ion batteries. However, pack with this type of BTMS typically suffers from high temperatures and large differences (∆T). To address issue, study conducted an electro-thermal coupled model to optimize the flow channel structure reducing maximum (Tmax) ∆T in “J-type” air-cooled BTMS. T...
