An electromagnetic scattering solution for the interaction between a dielectric cylinder and a slightly rough surface is presented in this paper. Taking the advantage of a newly developed technique that utilizes the reciprocity theorem, the difficulty in formulating the secondary scattered fields from the composite target reduces to the evaluation of integrals involving the scattered fields fro...

Due to the complex geometry and thermos-mechanical loading, cylinder heads are the most challenging parts among all parts engines. They must endure cyclic thermal and mechanical loading throughout their lifetime. Cast aluminum alloys are normally quenched after solution treatment process to improve aging responses. Rapid quenching can lead to high residual stress. Residual stress is one of the ...

A numerical study was conducted for natural turbulent and laminar convection induced by a circular hot obstacle in two different positions, the heat is introduced at inlet of cylinder inside cylinder. To determine effects on regime thermosiphon flow generated heated cylindrical channel, we suggest theoretical model using Navier–Stokes equations finite volume method. An experimental apparatus us...

Effect of time dependent normal transpiration on the problem of unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite circular cylinder moving simultaneously with time-depended angular and axial velocities and with time-dependent wall temperature or wall heat flux are investigated. The impinging free stream is steady with a strain rate . A re...

Abstract. A family of space-time finite element approximation schemes is presented for the nonlinear partial differential equations governing diffusion in the surface of a body of revolution. The schemes share with the partial differential equations properties ofconservation ofvolume and decrease of area. Numerical experiments are described showing that the result of the linear theory of small ...

This paper presents an experimental investigation of two different magnetorheological (MR) fluids, namely water-based and hydrocarbon-based MR fluids in compression mode under various applied currents. Finite Element Method Magnetics was used to predict the magnetic field distribution inside the MR fluids generated by a coil. A test rig was constructed where the MR fluid was sandwiched between ...
