Geomtry Optimization of an Ejector Based on the Two-Dimensional Distribution Model for Supermarket Application in Warm Climates

Abstract
This article introduces a thermodynamic model thatoffers the advantage of simplifying the calculationprocess and effectivelyexplains the intricate double-throttlingmechanismwithin the ejector. Initially, the article outlines the model'sassumptions and calculationprocedure. Subsequently, itassesses the influence of variousefficiencies. The model'svalidityisconfirmedthrough validation using multiple datasets. Furthermore, the ejector model isapplied to simulate a basicejectorrefrigeration(BER) cycle to ensureitsreliability and suitability for predicting the performance of thermodynamic cycles.
