FAST — A GENERALIZED FV SOLUTION OF CONVECTION‐DIFFUSION PROBLEMS BY MEANS OF MONOTONIC v‐SPLINES PROFILES

V. PENNATI, M. MARELLI, L.M. DE BIASE

In this paper new cubic v‐splines monotonic one‐dimensional profiles are presented, for the finite volume solution of convection‐diffusion problems. By studying the profile in…

A NUMERICAL STUDY OF NATURAL CONVECTION IN A VERTICAL ANNULUS WITH CONSTANT HEAT FLUX ON THE INNER WALL

J.G. WEI, W.Q. TAO

A numerical study of natural convection of air in a vertical annulus has been conducted, where the inner wall is heated with constant heat flux at its inner side, the outer wall…

NUMERICAL STUDY OF THE EFFECTS OF ROTATIONAL BUOYANCY ON FULLY DEVELOPED FLOW IN ROTATING RECTANGULAR DUCTS

T. BO, H. IACOVIDES

This article examines the influence of centrifugal buoyancy on the hydrodynamic and thermal behaviour in fully developed flow through an orthogonally rotating duct of aspect ratio…

APPROXIMATE ANALYTICAL SOLUTIONS FOR DIFFUSION PROBLEMS IN UNBOUNDED MEDIA AND THEIR APPLICATION IN INFINITE ELEMENTS

Y.C. LI

This paper presents approximate analytical solutions for the diffusion problems of a cylindrical hole in an infinite medium and a slot in an infinite medium with properly…

A RIEMANN‐PROBLEM‐BASED APPROACH FOR STEADY INCOMPRESSIBLE FLOWS

J. SHI, E.F. TORO

A new approach for solving steady incompressible Navier‐Stokes equations is presented in this paper. This method extends the upwind Riemann‐problem‐based techniques to viscous…
