On the one hand, a model describing the physico-chemical processes which occur within the bed of solid. On the other hand, C.F.D.the topic of this study, This model must include …

للكاتب : Elhabak, A.M. and Adly, M. Mech. Design & Prod. Dept., Faculty of Engineering, Cairo University   ABSTRACT The knee in the acoustic emission cumulative counts curve has been proposed as a possible solution to the absence of a characteristic yielding point in the stress-strain curve of composite materials. Yield strength could eventually be adopted in the engineering design as …

Dept., Banha university ABSTRACT The present experimental work concerns with forced convection heat transfer from vertical flat plate heated at constant heat flux subjected to normal air jet. This experimental work consists …

 للكاتب : N. M. Ashour Faculty Engineering, Mataria, Cairo, Helwan University, Egypt ABSTRACT On large thrust bearings, the geometry of the bearing pad surface is affected appreciably by deformation. In a spring supported thrust pad bearing, the deformation caused by the generated pressure and thermal gradient yields surface profiles of opposite shapes. The thermoelastic analysis performed here makes it possible …
