Performance prediction of steam ejector using computational fluid dynamics: Part 1. Validation of the CFD results

Effect of suction nozzle structure on reverse circulation performance of down-the-hole hammer drill bit

“…The most proper model should be selected against the flow physics, accuracy requirement, computing resources and simulation time. Since the RC DTH hammer drill bit was design with multiple ejectors, it is worthwhile to refer to the previous CFD simulations of ejector flow fields [18][19][20][21][22][23] before selecting the turbulence model. After long deliberation, the author selected the realisable k-ε model for the simulation.…”

Simulasi Numerik Aliran Melewati Nozzle Pada Ejector Converging – Diverging Dengan Variasi Diameter Exit Nozzle

“…Air (secondary fluid) yang terhisap kemudian bercampur dengan primary fluid pada mixing chamber ejector pada tekanan konstan. Campuran fluida berekspansi melewati difuser dan mengalami kenaikan tekanan serta penurunan kecepatan (subsonic velocity) [2]. Komponen utama ejektor adalah nosel.…”

Multidimensional modeling of condensing two-phase ejector flow

“…Analytical models have been made to better describe the experimental results. In the past few decades, CFD has been used to describe two-phase flow through nozzles, with some work particularly looking at the condensing ejector [8][9][10][11][12][13][14].…”

“…More recently (within the last decade), CFD simulations looking at flow (both single-phase and two-phase) through an ejector have become more complex in the aspect of modeling [9][10][11][12][13]. More sophisticated turbulence models have been used to better predict the flow and compressibility effects have been added too.…”
