Flow over arrays of cylinders different cross-sections has been an essential area research interest for a long time. For the estimation flow characteristics around cylinders, numerical simulation past four elliptic in square arrangement range spacing ratios is analysed this paper. Three considered present study are 3.45, 4.14 and 5.17. The results from compared with experimental findings obtain...

Motivated by recent developments in bio-inspired medical engineering micro-scale pumps, this paper, a three-dimensional sequential simulation of peristaltic micro-pump is described to provide deeper insight into the hydromechanics laminar, viscous flow propulsion. The Carreau and power-law models are employed for non-Newtonian behavior. commercial software package ANSYS Fluent utilized conduct ...

Liquid fuel has been the main source of energy in internal combustion engines (ICE) for decades. However, lithium-ion batteries (LIB) have replaced ICE environmentally friendly vehicles and reducing fossil dependence. This paper focuses on comparative analysis battery thermal management system (BTMS) to maintain a working temperature range 15–35 °C prevent runaway high gradient, consequently in...

Thailand’s beach had a severe coastal erosion problem at the end of rock dams called “end effect”. One innovative solutions to solve this is use derosion lattice (DL). However, since DL performance depends on installing conditions such as angle attack, placement position, terrain, and climate, computational fluid dynamics (CFD) was applied assess effect’s occurrence optimize DL’s installation. ...

A Nozzle is a mechanical device that uses pressure energy and fluid enthalpy to increase the outflow velocity control flow direction. To obtain nozzle duct's shock pattern, inside must be supersonic with Mach number greater than one. Experimentally, pattern obtained for 2 ratio (NPR) equivalent 7 below. For M = 2, needed NPR equal 7.82 correct expansion.. When 7.82, from nozzles under-expanded....

Motores de combustão interna que trabalham com combustível em condições supercríticas podem se beneficiar da baixa viscosidade, do alto coeficiente difusão massa e tensão superficial fluido. Além disso, o aquecido pode melhorar a partida motor reduzir emissão poluentes. Entretanto, para atingir essas condições, fluido necessita estar um estado temperatura reduzida pressão maiores 1, logo é nece...

  Computational algorithm was developed based on the well-known ANSYS Fluent  software package for studying unsteady wave outflow of a saturated liquid from high-pressure pipelines during emergency depressurization. The processes liquid, boiling as result depressurization vessels, have been investigated. system equations conservation mass, momentum, and energy in two-dimensional coord...

Abstract In the present work, we investigated effect of geometry open cell foam material on value pressure drop and heat flux. We create models porous media with an ordered (FCC, BCC, SC) disordered (DEM) structure different values porosity: 0.7; 0.75; 0.8. Numerical modeling was carried out in ANSYS Fluent software (v. 19.0) for various air flow velocities. At porosities 0.7 0.75 there is a no...

in this research, the numerical method of computational fluid dynamics and dimensionless parameter of froude number have been applied to determine the flow regime over ogee spillways.froude number is a dimensionless dynamic parameter calculated using the square root of the ratio of inertia force and gravitational force. considering that the study of the regimes of flow over hydraulic structures...
