چکیده
Due to the increasing energy cost, efficiency of industrial dryer as energy-intensive processes should be improved. The designer optimize design parameters drying equipment achieve minimum consumption. SST k-ω turbulence model is used simulate a real geometry for applications. For optimization impinging round jet, specific consumption set objective function minimized. jet surface distance, spacing, inlet velocity, angle, and velocity are chosen parameters. SHERPA search algorithm optimal point from weighted sum all objectives method. One correlation developed validated It found that succeeded with reasonable accuracy in reproducing experimental results. correlates high values low nozzle distance velocity. agreement prediction between numerical simulation data points deviate by less than 7%.

A Numerical Investigation of Impinging Jets
Steady, incompressible flow solutions are found numerically for a radially expanding liquid sheet in order to confirm analytical results for inviscid flow and to investigate viscous and nonlinear effects. An hp-finite element method is used to perform the numerical simulations. Comparisons are made to theoretical predictions of the radius where the sheet becomes unstable. To determine the criti...

In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using the RNG k-ε model. The results showed that the RNG k-ε model has more satisfactory predictions of the Nusselt number distribution. Comparisons ...

investigation on local scour phenomenon downstream of impinging jets is very complicated. different parameters such as geometry of stream, characteristics of flow and sediments have great influences on the scour phenomenon. the present study is preceded to numerical modeling of scouring by impinging jet via ssiim 2 model founded on a physical model tests. the numerical model is calibrated for r...
متن کاملNumerical Simulation of Primary Atomization of Non-Newtonian Impinging Jets
Newtonian impinging jets have been investigated for decades. However, limited is known about non-Newtonian impinging jets. The present work attempts to improve this situation by performing high-fidelity numerical simulations of non-Newtonian impinging jet dynamics. Emphasis is placed on the near field of the liquid sheet formed by the impingement of two shear-thinning (viscosity deceases with i...
