Effect of the Entrainment Flux Ratio on the Relationship between Entrainment Rate and Convective Richardson Number

Boundary-Layer Meteorology, 2007
The parameterization of the dimensionless entrainment rate (we/w*) versus the convective Richardson number (Riδθ) is discussed in the framework of a first-order jump model (FOM). A theoretical estimation for the proportionality coefficient in this parameterization, namely, the total entrainment flux ratio, is derived.

A one dimensional model for the determination of an ejector entrainment ratio

International Journal of Refrigeration, 2012
Abstract The proposed model is a new approach for the evaluation of the entrainment ratio of double choked ejectors, based on a perturbation procedure of linearized and axisymmetric supersonic flow. The model is developed in three regions: (i) the primary flow nozzle, (ii) the secondary flow channel, and (iii) the region of interaction between the ...

Development of the Technique for Calculating the Ejectors with Low Entrainment Ratios

Russian Aeronautics, 2018
This paper presents the results of an investigation of ejectors with the low entrainment ratio. A technique for calculating the ejectors with a curvilinear axis has been developed. Comparative studies of the performance characteristics of ejectors with the rectilinear axis of the mixing chamber and the curvilinear initial section of the mixing chamber ...

Numerical study on the auxiliary entrainment performance of an ejector with different area ratio

Applied Thermal Engineering, 2021
Abstract In this paper, an ejector-based multi-evaporator refrigeration system is proposed for the tropical region refrigerated trucks. CFD simulations are performed to study the auxiliary entrainment effect of the ejector operated in air-conditioning - freezing mode.
