A finite volume method for the solution of convection—diffusion 2d problems by a quadratic profile with smoothing

L. De Biase, F. Feraudi, V. Pennati

A new finite volume (FV) method is proposed for the solution ofconvection‐diffusion equations defined on 2D convex domains of general shape.The domain is approximated by a…

A model for the analysis of concrete dams due to environmental thermal effects

L. Agullo, E. Mirambell, A. Aguado

In this article, an analytical model is presented for the simulation ofthe thermal behaviour of dams that are subjected to environmental thermalaction during service. The method…

Heatline visualization in turbulent flow

Sukanta K. Dash

The concept of a heat function is introduced to visualize the path ofheat flow in a buoyancy‐driven turbulent flow heated vertical flat plate. Thevelocities and the temperature…

Rama Subba Reddy Gorla, M.A. Mansour, A.A. Mohammedien

An analysis is presented to study the effects of buoyancy on forcedconvection in an axisymmetric stagnation flow of micropolar fluids over avertical cylinder with constant or…

Cyclic phase change with fluid flow

V.R. Voller, P. Felix, C.R. Swaminathan

Cyclic phase change involves the successive freezing and melting of aregion driven by a boundary temperature that cycles above and below thesolid/liquid phase change temperature…

Simulation of laminar confined flow past a circular cylinder with integral wake splitter involving heat transfer

B.S.V.P. Patnaik, K.N. Seetharamu, P.A. Aswatha Narayana

A finite element method is used to study the effect of flow past acircular cylinder with an integral wake splitter. A fractional step algorithmis employed to solve the…
