Two empirical models are presented in order to determine the dispersion number and mean residence time for the pilot scale column cell in the Sarcheshmeh copper complex. To check the accuracy of these models a series of ...

In two phase flow investigation, there is a need for robust methods capable of predicting interfaces, in addition to treating the traditional governing equations of fluid mechanics (Navier-Stokes Eqs.). Such methods in a ...

This paper is concerned with finite element model updating of rotating structures using measured vibration test data. The use of both deterministic and stochastic optimisation techniques was investigated in order to minimise ...

Unsteady incompressible unidirectional third-grade fluid past an infinite porous wall is considered in the presence of Hall current. The plate at the lower boundary y=0 is executing sinusoidal oscillations in its own plane ...

At McGill University, Canada, a successful Knelson technology for gravity recoverable gold (GRG) has been used to process more than 200 representative gold ore samples all over the world since the early 1990s. In recent ...

Selection of tool steels is not limited to one type of steel for satisfying customer needs. On the other hand, technical specifications of tool steels are not absolute and it consistently deviates from the mean. Thus in ...
