Steady And Transient Study Of Conjugate Heat Transfer In Regenerative Cooled Nozzle, Khaled Bensayah, Khadidja Kamri

Emirates Journal for Engineering Research

The Heat transfer is one of the most serious challenges that exist in a supersonic nozzle flow. The combustion chamber wall and the nozzle are exposed to high-temperature gases during combustion and gas expansion, which can eventually lead to structural failure. This paper reports a computational study of steady and transient conjugate heat transfer in regenerative water cooled nozzle. Numerical computation solved Reynolds-averaged equations based on RSM-Omega turbulence model coupling with solid-phase heat conduction equation and with coolant-phase. The effect of four inlet cooled approach length 0 inch, 6 inch, 12 inch and 18 inch are studied and validated against …

Analysis Of Thin Plates In Bending By New Rectangular Strain Based Element., Samira Chichoune, Cherif Rebiai

Emirates Journal for Engineering Research

Abstract

This paper deals with the development of a new simple four node rectangular finite element for bending analysis of thin plates. The displacement s field of this element is based on the assumed functions for the various strains satisfying the compatibility equations. This developed element has three degrees of freedom at each node (two rotations and one translation), and it passed successfully benchmark tests in the case of thin plates without shear locking phenomena. The obtained numerical results using the developed element converge toward both analytical and reference solutions.
