The context of this paper is the simulation parameter-dependent partial differential equations (PDEs). When aim to solve such PDEs for a large number parameter values, Reduced Basis Methods (RBM) are often used reduce computational costs classical high fidelity code based on Finite Element Method (FEM), Volume (FVM) or Spectral methods. efficient implementation most these RBM requires modify co...

This study develops robust numerical algorithms for the simulation of three-phase (solid-liquid-gas) boiling and bubble formation problems in rectangular channels.

Water is used base-l...

In this paper, symmetric water entry of twin wedges is investigated for deadrise angle of 30 degree. Three numerical simulation of a symmetric impact, considering rigid body dynamic equations of motion in two-phase flow is presented. The two-phase flow around the wedges is solved by Finite Element based on Finite Volume method (FEM-FVM) which is used in conjunction with Volume of Fluid (VOF) sc...

A recent emergence of the Finite Volume Method (FVM) in structural analysis promises a viable alternative to the well-established Finite Element solvers. In this paper the linear stress analysis problem is discretised using the practices usually associated with FVM in uid ows. These include the second-order accurate discreti-sation on Control Volumes of arbitrary polyhedral shape; segregated so...

The radiative heat transfer problem is investigated numerically for 2D complex geometry biomass pyrolysis reactor composed of two pyrolysis chambers and a heat recuperator. The fumes are a mixture of carbon dioxide and water vapor charged with absorbing and scattering particles and soot. In order to increase gases residence time and heat transfer, the heat recuperator is provided with many incl...

the forced convection heat transfer of turbulent al2o3-water nanofluid flow inside the grooved tubeswith the different aspect ratio of the rectangular grooves is numerically investigated. the governingequations have been solved using finite volume method (fvm) coupled with simple algorithm. it isassumed the heat flux is constant on the grooved walls. the single-phase approach is applied for the...

The time-dependent equation of radiative transfer is solved for a participating medium housed in an axisymmetric cylindrical enclosure by both the discrete-ordinates method and the finite volume method. Many heat transfer processes, including absorption of renewable and sustainable solar energy in a solar receiving tube for use in power plants, can be modeled in a cylindrical enclosure. Steady-...

The understanding of flow problems, and finding their solution, has been important for most of human history, from the design of aqueducts to boats and airplanes. The use of physical miniature models and wind tunnels were, and still are, useful tools for design, but with the development of computers, an increasingly large part of the design process is assisted by computational fluid dynamics (C...

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 ...
