Solidification Of Steel Billets In Continuous Casting
(
Qatar University
, 1991 , Article)
For practical operation, it is necessary to know how the solidification of liquid steel progresses i.e. when and where a strand has completely solidified. Decisions on, the casting speed, the spray water flow rates and ...

(
Qatar University
, 1992 , Article)
In this paper, an assessment of the performance of one of the multistage flash (MSF) desalination units operating in conjunction with the gas-turbine cogenera-tion power plant in Qatar is carried out under different operating ...
Study of A Time Dependent Double -Diffusive Salinity Problem
(
Qatar University
, 1989 , Article)
The time-dependent, double diffusive stability problem for a horizontal layer of salty water bounded by two rigid isothermal surfaces is analyzed using a linear perturbation technique. Initially, the layer is subjected to ...
