The effects of density extremum and rotation on the onset of thermal instability

J.P. Pascal, S.J.D. D'Alessio

This paper addresses the onset of Be´nard convection on a rotating horizontally confined layer of water near the temperature of maximum density that is heated from below. A…

Heat transfer to pulsating turbulent flow in an abrupt pipe expansion

S.A.M. Said, M.A. Habib, M.O. Iqbal

A numerical investigation aimed at understanding the flow and heat transfer characteristics of pulsating turbulent flow in an abrupt pipe expansion was carried out. The flow…

3D numerical simulation of on ground Marangoni flow instabilities in liquid bridges of low Prandtl number fluid

M. Lappa, S. Yasushiro, N. Imaishi

The influence of gravity on the Marangoni flow instability in half zone liquid bridges in the case of liquid metals is investigated by direct 3D and time‐dependent simulation of…

Bioconvection of negatively geotactic microorganisms in a porous medium: the effect of cell deposition and declogging

A.V. Kuznetsov, N. Jiang

Mechanisms of deposition and declogging are considered while formulating a new continuum model for bioconvection in a dilute suspension of motile, negatively geotactic…

Linear feedback control for convection‐diffusion

Christos Kavouklis, Graham F. Carey

This study is concerned with linear feedback control in finite element modeling of transient convection‐diffusion in an incompressible fluid. Our aim is to introduce a linear…

Numerical model for vacuum infusion manufacturing of polymer composites

H. Magnus Andersson, T. Staffan Lundström, B. Rikard Gebart

The focus is set on the development and evaluation of a numerical mgodel describing the impregnation stage of a method to manufacture fibre reinforced polymer composites, namely…
