FAST, POSITIVE AND CONSERVATIVE SCHEME FOR CHEMICALLY REACTIVE HYPERSONIC FLOW

ENRICO BERTOLAZZI, VINCENZO CASULLI

A finite difference method for solving the quasi one‐dimensional non‐equilibrium hypersonic flow equations in a diverging nozzle is presented and discussed. In chemically reacting…

VORTEX INITIATION DURING DYNAMIC STALL OF AN AIRFOIL

I.P. ITTY, J.R. LEITH

The flow field around an oscillating airfoil is evaluated numerically, using the stream function‐vorticity formulation of the Navier‐Stokes equations. An algebraic turbulence…

A MATHEMATICAL MODEL AND COMPUTER AIDED DESIGN FOR THE TEMPERATURE DISTRIBUTION IN AN OPEN HYDRAULIC SYSTEM

I. AL NATOUR, M.S.J. HASHMI

Hydraulic systems that operate for long periods of time eventually develop high oil temperatures that have damaging effects on machine performance. If the temperature rise is…

FINITE ELEMENT ANALYSIS OF TWO DIMENSIONAL RAYLEIGH‐BENARD CONVECTION WITH GRAVITY MODULATION EFFECTS

BALASUBRAMANIAM RAMASWAMY

Sinusoidal gravity modulation fields imposed on two‐dimensional Rayleigh‐Benard convection flow are studied to understand the effects of periodic source (g‐jitter) on fluids…

ANALYSIS OF NATURAL CONVECTION MELTING OF A VERTICAL ICE CYLINDER INVOLVING DENSITY ANOMALY

YONGKE WU, MARCEL LACROIX

A numerical study is reported of natural convection melting of ice within a vertical cylinder. A stream function‐vorticity‐temperature formulation is employed in conjunction with…

A METHOD FOR ANALYSING THE EFFECT OF FLOW ON HEAT TRANSFER IN DIE CASTING

M.R. BARONE, E. KOCK

A new method has been developed for determining the effect of flow on heat transfer in die casting during steady production. Aside from the assumption that the casting is thin in…

SHORT COMMUNICATION: USE OF THE KIRCHHOFF TRANSFORMATION IN FINITE ELEMENT ANALYSIS

DAN GIVOLI

The Kirchhoff transformation, in conjunction with the finite element method, is proposed as a tool in solving non‐linear heat conduction problems. A very simple way to obtain the…
