Natural convection heat transfer from discrete heat sources in a three dimensional enclosure

Tawhid Ezaz (Department of Mechanical Engineering, 2005-07)

Flow in a rectangular enclosure with an uniform heat flux applied across the vertical sidewall and with the opposite vertical surface cooled to a uniform low temperature has been numerically studied. Computations has ...
Stability and stress analysis of ellipsoidal pipe reducers

Zahid Hussain, Syed (Department of Mechanical Engineering, 2003-09)

The present research work deals with the stability and stress analysis of ellipsoidal pipe reducers. Stability of the shells have been determined from the solution of nonlinear governing equations of axisymmetric ...
Development of turbulent boundary layer in sudden change of upstanding surface roughness

Haldar, Shyama Brata (Department of Mechanical Engineering, 1987-10)

Turbulent flows over the flat surface undergoing a sudden change of surface roughness were studied experimently. The experiment was carried out in a wind tunnel test section, the floor of which was used as t'lesurface ...
