Project Summary

The ongoing Energy crisis demands a focus on complete and effective utilization of available waste heat energy. This led to development of low temperature operating device such as ejector which utilizes waste heat for compression purposes. The performance prediction of ejector is mainly done by expensive numerical simulations and some mathematical correlation that can predict ejector performance with somewhat reasonable accuracy. The problem with these mathematical correlations is that they require laborious and time consuming pre calculations. This research aims at developing a single mathematical correlation that can predict the ejector performance with reasonable accuracy thus eliminating the need for lengthy and laborious pre calculations and also validating the results with CFD simulation.

Project Objectives

The Project objective is the development of a Mathematical correlation that can predict the performance of Ejector using a single correlation that incorporates all the parameters that actually influence the performance of Ejector. Secondly, the developed mathematical correlation is to be validated using a CFD(Computational Fluid Dynamic) simulation on commercially avalable software ANSYS FLUENT v19.0.

Project Implementation Method

As the main objective of the project is to develope a mathematical correlation, for this to happen:

The first requirement is solving a mathematical model of ejector,in this case model is taken from already published research paper.

Secondly, on the basis of analytical solution previously done performance evaluation or parametric study is done using different geometry arrangements and different fluid properties.

In the third step, on the basis of results of paramteric study a mathematical correlation using statistical methods is developed.

Lastly, the correlation developed is validated through a numerical simulation on ANSYS FLUENT v19.0.

Benefits of the Project

The main benefit of this project is to provide a quick and accurate way of selecting an ejector for industrial or research use.

Moreover, this project will act as a contribution in ongoing research on ejectors providing details of flow behaviour in the ejector also covering the flow discontinuties like normal and oblique shockwaves. 

Technical Details of Final Deliverable

The final deliverable will contain a piece of software based on matlab code,that can help industries or researchers to select the ejector given inlet pressure and temperature of flow and also the desired pressure and flowrate at outlet of ejector. Also it contains an empirical correlation for ejector performance evaluation.

Lastly, a CFD model of ejector will be provided for validation of analytical resultsa and also for graphical analysis of flow flowing through the ejector.
