Implicit modified enthalpy method with application to thin film melting

Christopher K. Hess, Ioannis N. Miaoulis

During the thermal processing of thin films in which low intensity lineheat sources are used, extended processing times are often required to reachsteady state (˜15 sec). In…

A direct numerical simulation of transition in mixed convection flows between two heated parallel plates

C.C. Hao, J.N. Chung

This paper seeks to increase our understanding on the fluid mechanicsand heat transfer in a transitional mixed convection flow between twovertical plates. Direct numerical…

Numerical experiments on laminar natural convection in rectangular cavities with and without honeycomb‐structures

H. Schweiger, A. Oliva, M. Costa, C.D. Pérez Segarra, A. Ivancić

Two‐dimensional finite difference calculations are carried out tostudy laminar flow in longitudinal and transverse convection rolls for threedifferent geometries: a single…

A numerical optimization procedure for complex pipe and duct network design

E.H. Mathews, P.A.J. Köhler

The design of optimum pipe and duct networks with available proceduresis difficult, if not impossible. A more efficient procedure that willautomatically produce the optimum design…

Transient conjugated heat transfer in concentric annuli

M.A.I. El‐Shaarawi, M.A. Al‐Nimr, M.A. Hader

The paper presents a finite‐difference scheme to solve thetransient conjugated heat transfer problem in a concentricannulus with simultaneously developing hydrodynamic and…
