Non‐polynomial spline method for the solution of the dissipative wave equation

Talaat S. El Danaf, Faisal E.I. Abdel Alaal

The purpose of this paper is to propose a non‐polynomial spline‐based method to obtain numerical solutions of a dissipative wave equation. Applying the Von Neumann stability…

Convective heat transfer prediction for an axisymmetric jet impinging onto a flat plate with an improved k‐ ω model

S. Kubacki, E. Dick

This paper aims to provide improvements to the newest version of the k‐ ω turbulence model of Wilcox for convective heat transfer prediction in turbulent axisymmetric jets…

Simulation of soliton‐like waves generated by topography with conservative fully discrete shallow‐water arbitrary‐order schemes

Yuri N. Skiba, Denis M. Filatov

The purpose of this paper is to suggest a new approach to the numerical simulation of shallow‐water flows both in plane domains and on the sphere.

Impulsive Falkner‐Skan flow with constant wall heat flux: revisited

Simon D. Harris, Derek B. Ingham, Ioan Pop

The purpose of this paper is to present a numerical and an analytical study of the fluid flow and heat transfer in the unsteady, laminar boundary layer resulting from the forced…

Numerical simulation of flow through tube bundles in in‐line square and general staggered arrangements

Behzad Ghadiri Dehkordi, Hamed Houri Jafari

The purpose of this paper is to outline more computational schemes which provide a low computational cost approach to analyze flow characteristics through tube bundles. Flow…
