AN UPWIND UNSTRUCTURED GRID SOLUTION ALGORITHM FOR COMPRESSIBLE FLOW

S. SOLTANI, K. MORGAN, J. PERAIRE

An upwind unstructured grid cell‐centred scheme for the solution of the compressible Euler and Navier‐Stokes equations in two dimensions is presented. The algorithm employs a…

FINITE ELEMENT ANALYSIS OF THE EFFECT OF RADIUS RATIO ON NATURAL CONVECTION IN AN ANNULAR CAVITY

B.V.K. SATYA SAI, K.N. SEETHARAMU, P.A. ASWATHA NARAYANA, J.N. REDDY

A finite element method based on the Eulerian velocity correction method has been used to analyse the laminar natural convection in an annular cavity. Unsteady, incompressible…

A FULLY CONSERVATIVE NUMERICAL SCHEME FOR A KIND OF GENERALIZED 3D PERIODIC EULER EQUATIONS

TOMÁS CHACÓN REBOLLO

A kind of generalized 3D Euler equations with periodic boundary conditions, that describes the behaviour of the small scale flow in a turbulence model is solved. A fully…

LAMINAR FULLY DEVELOPED INCOMPRESSIBLE FLOW WITH MIXED CONVECTION IN INCLINED TUBES

J. ORFI, N. GALANIS, C.T. NGUYEN

The effects of tube inclination and Grashof number on the fully developed hydrodynamic and thermal fields are investigated numerically for laminar ascending flow of air and water…

NUMERICAL ANALYSIS ON STROUHAL FREQUENCIES IN VORTEX SHEDDING OVER SQUARE CYLINDERS WITH SURFACE SUCTION AND BLOWING

LISA M. LING, BALASUBRAMANIAM RAMASWAMY, RUBEN D. COHEN, TSWEN‐CHYUAN JUE

The effects of normal surface suction and blowing on the Strouhal frequencies in vortex shedding over porous square cylinders was analysed numerically. The general characteristics…
