A new modified homotopy perturbation method with two free auxiliary parameters for solving MHD viscous flow due to a shrinking sheet

Behrouz Raftari, Ahmet Yildirim

The purpose of this paper is to introduce a new version of the homotopy perturbation method (HPM) for solving the magnetohydrodynamic viscous flow due to a shrinking sheet.

Simulating a Gaussian random process by conditional PDF

Jernej Klemenc, Matija Fajdiga

One of the biggest problems in an R&D process is the acquisition of information about the structure dynamic loads, which are needed to reliably prove the structure's durability…

Verifying performance of axial‐flow pump impeller with low NPSHr by using CFD

Wen‐Guang Li

A method for optimizing net positive suction head required of axial‐flow pumps has been proposed by the present author, which is based on the two‐dimensional potential flow model…

Hybrid‐Trefftz finite element method for heat conduction in nonlinear functionally graded materials

Zhuo‐Jia Fu, Qing‐Hua Qin, Wen Chen

The purpose of this paper is to develop a hybrid‐Trefftz (HT) finite element model (FEM) for simulating heat conduction in nonlinear functionally graded materials (FGMs) which can…

Prediction of strength of reinforced lightweight soil using an artificial neural network

H.I. Park, Y.T. Kim

Reinforced lightweight soil (RLS) consisting of dredged soil, cement, air‐foam, and waste fishing net is considered to be an eco‐friendly backfilling material because it provides…

Improving reciprocating compressor performance using a hybrid two‐level optimisation approach

Ibrahim A. Sultan, Azfar Kalim

This paper seeks to describe a design approach which can be used to manufacture better‐performing reciprocating compressors. This design approach relates the drive kinematic…
