The computational fluid dynamics is concentrated on the forced air cooling of the CPU using a heat sink. This paper utilizes CFD to identify a cooling solution for a desktop computer, which uses an 80 W CPU maximum whereas this number will be increased in the range of 70-120W in the forthcoming desktop computer systems. This paper considers the optimal plate fin heat sink design and cylindrical...

Auxiliary ventilation of the blind development heading in underground mines is one of the most challenging work activities amongst mining underground operations. The auxiliary forcing ventilation system provides positive pressure, cooling, controlling gas layering, and removing diesel fumes and dust levels from development headings, stopes, and services facilities. The effectiveness of the auxi...

This paper uses CFD software ANSYS Fluent, based on RSM Reynolds stress model and VOF two-phase flow model, to calculate the turbulent field inside ∅75mm heavy dispersed phase particle separation cyclone. Combined with experimental working parameters under different inlet pressures, results were compared. Check accuracy of formula calculation numerical simulation results. The show that air colu...

The aim of the study is to simulate functionality a HVAC system in different situations, summer and winter time, using specialized software ANSYS-Fluent. A 2D building model was realized simulating internal conditions represented main elements study. There are studied indoor air temperature velocity conditions. results presented as graphs/plots spectra interest parameters. simulation ANSYS-Flue...

The paper considers a variant of the problem modeling flow around developed wind turbine. Building CAD model Fig. 1. was carried out in SolidWorks environment, where main geometric dimensions were specified. Since task is reduced to flat task, 2D design mode chosen.

Temperature and pressure as two important working conditions of the air ejector are very to its performance. Taking installed in a power plant an example, using ANSYS-FLUENT software, three-dimensional simulation operation under different temperature is carried out, relations between pressure, temperature, inlet gas flow rate ejection coefficient given. The results show that have some influence...

Lithium-sulfur batteries appear to be an exciting technology for energy storage due their many advantageous properties. Due its low weight and high energy, this could used in aviation, aerospace or heavy electric vehicles even mobile applications. This article investigates possible approaches modelling of lithium-sulfur batteries. A new method using Ansys Fluent add-on Multi-Scale Multi-Domain ...

The article is focused on the mathematical simulation of temperature influence shear stress during mineral oil flow. rotary rheometer used to measure stress. It works principle torque measurement when spindle rotates in container with measured liquid. rotating together forms hollow cylinder which filled by oil. evaluated for various temperatures. software ANSYS Fluent evaluate partial numerical...

The main causes of aerodynamic drag for automotive vehicles are the flow separation at rear end vehicles. By reducing force, it is possible to increase fuel economy. Aerodynamic component i.e. Frontal Deflectors (FD) commonly used on trucks prevent separation. themselves do create drag, but they also reduce drags by preventing downstream. aim this paper quantify effect frontal deflectors improv...
