INVESTIGATION OF PROPORTIONAL MIXING

we present a method for thorough and perfect mixing of liquid with two different temperaturesin exact proportion by using the Venturi principle. A mathematical model for this method is formulated by coupling continuity equation, Bernoulli’s equation and momentum equation. Computations are done for a tube with a nozzle, attached to the throat section of the venturi; the computationsresult shows the closeness of the values with the mathematical model. Computations are also performed where the mixing is effective for the nozzle position to determine the results and find the correlations between them.The Computed flow patterns for various parameters of the venturi such throat length, throat diameter and Reynolds number are analysed to understand the venturi principle to accomplish required proportional mixing.The effective use of CFD results in reduced fabrication of venturi for trial and error methods which ultimately results in practical simplicity. Finally the obtained results for various cases are compared with theoretically obtained results and comparative study is formulated.
