In-depth radiation absorption in pyrolysis models is commonly modeled with Beer’s law using a constant coefficient. This approximation neglects the effects of spectral variation coefficient, material emissions, and directional dependency penetrated thermal radiation. research aims to address importance these factors flammability analysis black poly(methyl methacrylate) (PMMA). Accordingly, mode...

Peristaltic flow is important in many biological processes, including digestion, and forms an component of any silico model the stomach. There a clear need to verify simulations such flows. An analytical solution was identified that can be used for verification, which gives equation net volumetric over cycle applied sinusoidal wall motion. Both smooth particle hydrodynamics (SPH) code (from CSI...

Finite volume method is a method of choice for hyperbolic systems of conservation laws such as the Euler equations of gas dynamics. FVM is often combined with mesh adaption techniques. Since rigorous treatment of hyperbolic systems is far beyond current state of research, we use initial-boundary value problem for scalar conservation law as a model case. We estabilish basic form of an algorithm ...

In this article, a laminar magnetohydrodynamics (MHD) developing flow of an incompressible electrically conducting fluid subjected to an external magnetic field is considered. The aim of the study is to propose a correlation for computing the development length of the laminar MHD developing flow in a pipe. A numerical approach is considered to solve the problem. In the first step, the numerical...

This research numerically surveys the effects of several main parameters an agitated anaerobic digester on mixing rate and power input. The numerical simulation is handled applying finite volume method (FVM), it validated with available experimental data. results indicate that doubling blade length enhances by 39.9% makes input enhance 13.5 times; increasing number blades (from 4 to 6) improves...

Abstract CFD is a numerical approach used to solve fluid problems. In the simulation process, meshing stage crucial produce high accuracy. Meshing process where geometric space of an object broken down into many nodes translate physical components that occur while representing object’s shape. The research objective was analyze characteristics mesh technique in Finite Volume Method (FVM) using R...

During Wire Arc Additive Manufacturing (WAAM), an arc welding process is used to deposit material. The evolution of temperature during the a key aspect affecting accuracy and mechanical properties. possibility predict therefore crucial for planning deposition sequence. Currently, Finite Element Method (FEM) well-established solution simulations. However, computational efficiency typically achie...

In the present study, effect of receiver position error on optical and thermal performance a parabolic trough collector (PTC) has been studied. Optical analysis PTC carried out by using Monte Carlo ray tracing (MCRT) method. The solar heat flux profile obtained from is coupled with finite volume method (FVM) to study PTC. Simulations have done for experimental SEGS LS2 used in Sandia National L...

In this paper, the cooling performance of water-cooled heat sinks for heat dissipation from electronic components is investigated numerically. Computational Fluid Dynamics (CFD) simulations are carried out to study the rectangular and circular cross-sectional shaped heat sinks. The sectional geometry of channels affects the flow and heat transfer characteristics of minichannel heat sinks. T...
