ABSTRACT

Hot isostatic processing (HIP) is the latest method to produce open porous materials, such as ceramics or metals. In this review paper, features and applications of HIPed porous materials are described. Sintering behavior under high pressure gas is also discussed in order to understand how porous materials are obtained by this method. HIPed porous materials have higher open porosity, higher mechanical strength, narrower pore size distribution and higher fluid permeability ....etc

THEORETICAL ANALYSIS FOR STUDYING THE
FRETTING WEAR PROBLEM OF STEAM GENERATOR
TUBES IN A NUCLEAR POWER PLANT
ABSTRACT


Fretting, which is a special type of wear, is defined as small amplitude relative motion along the contacting interface between two materials. The structural integrity of steam generators in nuclear power plants is very much dependent upon the fretting wear characteristics of Inconel 690 U-tubes. In this study, ....etc

download ppt on ic engine with homogeneous combustion in a porous medium

Abstract
At present, the emissions of internal combustion engines can only be improved by catalytic treatments of the exhaust gases. Such treatments, however, result in high costs and relatively low conversion efficiency. This suggests that a new combustion technique should be developed to yield improved primary combustion processes inside the engine with drastically reduced exhaust gas emissions. In this paper,. We report on such a technique that is applicable to direc ....etc

seminor ppt on new concept of homogeneous combustion in i c engines using the porous medium combustion engine

The paper summarizes the knowledge concerning porous media combustion techniques as applied in engines. One of most important reasons of this review is to introduce this still not well known technology to researchers doing with internal combustion engine processes, thermal engines, reactor thermodynamics, combustion, and material science. The paper gives an overview of possible applications of a highly porous open cell structures to in ....etc
