Numerical simulation of natural convection and phase‐change in a horizontal Bridgman apparatus

Diego Celentano, Marcela Cruchaga, Jorge Romero, Mohammed El Ganaoui

The purpose of this paper is to present a 2D numerical simulation of natural convection and phase‐change of succinonitrile in a horizontal Bridgman apparatus. Three different heat…

The use of variational iteration method and homotopy perturbation method for solving two nonlinear equations

Manel Labidi, Khaled Omrani

The purpose of this paper is to implement variational iteration method (VIM) and homotopy perturbation method (HPM) to solve modified Camassa‐Holm (mCH) and modified…

Mixed convection flows in a vertical plane duct preceded by a sudden expansion

Essam Moustafa Wahba

The purpose of this paper is to numerically investigate the effects of different heating and cooling scenarios on the flow structure in a vertically oriented plane sudden…

Effect of chemical reaction on heat and mass transfer by mixed convection flow about a sphere in a saturated porous media

A.M. Rashad, A.J. Chamkha, S.M.M. El‐Kabeir

The purpose of this paper is to study the effects of chemical reaction on mixed convection flow along a sphere in non‐Darcian porous media.

Composite element algorithm for the thermal analysis of mass concrete: Simulation of cooling pipes

Sheng‐hong Chen, Peifang Su, Isam Shahrour

Pipe cooling is an important measure for controlling the temperature in mass concrete. Since the temperature field in mass concrete containing cooling pipes is unsteady and…

He's homotopy perturbation method for solving the fractional KdV‐Burgers‐Kuramoto equation

Sefa Anıl Sezer, Ahmet Yıldırım, Syed Tauseef Mohyud‐Din

The purpose of this paper is to directly extend the homotopy perturbation method (HPM) that was developed for integer‐order differential equation, to derive explicit and numerical…
