A study of fluid flow simulation in convergent-divergent nozzles

A study of geometry nozzle is particularly important in optimizing the quantity of coolant in terms to minimize that quantity or coolant can be used for lubrication of machines moving parts. Coolants can be from the simplest (water, air) as well as a mixture of liquid (emulsions) to achieve a good cooling in function of temperature that develops in the area concerned. The study from this paper proposes an analysis and a simulation of flow through the convergent-divergent nozzle type to optimize them and to use a minimum quantity of coolant or lubricant. This study is focus on the analysis of cooling systems for cutting processes on machine tools. (paper)
