The Effects of Operational Parameters on the Efficiency of a Mixer-Settler Extractor
Volume 2, Issue 1 , January 2005, Pages 10-23

  The effects and influences of various operational parameters on the efficiency of mixer-settlers are thoroughly studied in this paper. One of the most important factors in designing a mixer-settler is to obtain an optimum operational extraction and overall efficiency. These two factors are dependent ...  Read More

A New Model for Prediction of Heat Eddy Diffusivity in Pipe Expansion Turbulent Flows
Volume 2, Issue 1 , January 2005, Pages 24-33

  A new model to calculate heat eddy diffusivity in separating and reattaching flows based on modification of constant Prt is proposed. This modification is made using an empirical correlation between maximum Nusselt number and entrance Reynolds number. The model includes both the simplicity of Prt=0.9 ...  Read More
