Abstract An unsteady local heat transfer in an air synthetic non-steady-state jet impingement onto a flat plate with variation of the Reynolds number, nozzle-to-plate distance and pulses frequency is experimentally numerically studied. Measurements averaged pulsating at stagnation point are conducted using flux sensor. The axisymmetric URANS method stress model used for numerical simulations. F...
Jet-wiping is a hydrodynamic method for controlling the liquid film thickness in a coating process. In industrial conditions, the jet is generally turbulent. When the jet wipes a liquid film, it usually induces violent film instability called splashing. The instability is characterized by the ejection of droplets from the runback flow. Consequently, it can degrade the final coating quality sinc...
An integrated process which is proposed for improving dust removal efficiency of cyclones in another paper is considered here for simulation by Artifitial Neural Networks (ANNs) and hybrid ANN and Genetic Algorithm (GA). The process incorporates of two cyclones coupled with a specially designed cylindrical chamber, which includes a rotating tube inside it with air-impinging nozzles drilled on t...
