Three dimensional MHD nanoluid stagnation point low withhigher order chemical reaction

In hot and dry climates, evaporative cooling of the air by water spray can be applied in several requirements, such as condensers which airflow is precooled before it reaches condenser. The interaction between droplets a complicated two-phase flow that affected parameters. Here, an Eulerian-Lagrangian 3D model was developed to investigate influence important parameters on performance rectangular duct. evaluated include number nozzles, inlet rate, rate. results represented growth nozzles causes reduction efficiency. Thi s due decrease retention time within duct increasing at constant total rate cases. maximum minimum efficiency belong cases with one nozzle 20 l/h four 5 l/h, respectively. difference 3 4 less than 1.8%. Moreover, from 0.5 2 (by 300%) makes up 58.6%.
