Avaliação da hidrodinâmica de um prato misto (perfurado e valvulado).

Abstract

The objective of this research is to study the variation of some hydrodynamics parameters (pression dropping in the dry and irrigated plates) a function of the flow rate of gas, perfuration number, weight of the valves and the level of the liquid on the perfurated, valvulcd and mixed plates. From this study were adjusted the obtained results to cquactions from the literature by computational numeric methods and under the snmc thoughts news cquactions were suggested to changeable parameters for each type of plate. The thermal behaviour was investigated to the lenght of the irrigated plates with the objective to find out the great area of heat transference using hot water and cold air.
