Natural convection in porous cylindrical annuli

J.P. Barbosa Mota, E. Saatdjian

Natural convection in a porous layer between two horizontal, concentriccylinders is investigated numerically by solving the 2‐DDarcy‐Boussinesq equations on a very fine grid…

Numerical experiments in turbulent natural and mixed convection in internal flows

C.D. Pérez‐Segarra, A. Oliva, M. Costa, F. Escanes

In this paper a numerical simulation, based on finite differencetechniques, has been developed in order to analyse turbulent natural andmixed convection of air in internal flows…

Convective discretization schemes for the turbulence transport equations in flow predictions through sharp u‐bends

T. Bo, H. Iacovides, B.E. Launder

This paper presents finite volume computations of turbulent flow througha square cross‐sectioned U‐bend of curvature strong enough(Rc/D =0.65) to cause separation. A zonal…

A locally modified second order upwind scheme for convection terms discretization

G. Papadakis, G. Bergeles

A finite difference scheme for convection term discretization, calledBSOU (stands for Bounded Second Order Upwind), is developed and itsperformance is assessed against exact or…

Accurate animation of the thermo‐fluidic performance of the pressure‐wave machine and its balanced material operation

H. Oberhem, H.A. Nour Eldin

Modelling, computation and performance animation of turbomachinerysystems has recently enjoyed remarkable attention in CAD research. This isalso reflected its application to…

A well‐behaved scheme to model strong convection in a general transport equation

A. Pascau, C. Pérez, D. Sánchez

A new discretization scheme named NOTABLE (New Option forthe Treatment of Advection in the Boundary Layer Equations) ispresented. Despite its name, this scheme is intended to be…
