A CONTRIBUTION TO THE UNDERSTANDING OF CAVITATION EFFECTS IN DIESEL INJECTOR NOZZLES THROUGH A COMBINED EXPERIMENTAL AND COMPUTATIONAL INVESTIGATION.
In this paper a combined experimental and computational study was carried out in order to assess the ability of a Homogeneous Equilibrium Model in predicting the experimental behaviour observed from the hydraulical characterization of a nozzle. The nozzle used was a six-orifice microsac nozzle, with cylindrical holes, and therefore inclined to cavitate. The experimental results available for the validation purpose comprised measurements of mass flow rate and spray momentum flux, which correctly combined provide also fundamental information such as discharge coefficient, nozzle exit effective velocity and area contraction. The model was proved to be able of
Production planning is one of the important activities in the company, each of its activities involve decision making. To be able to meet the ::: demand of its customers continuously, companies must have good planning. Therefore, this paper discusses the application of Fuzzy ::: inference system Tsukamoto for decision making in production planning at the company's crude palm oil [CPO). The purpose of this ::: research is to assist the production manager to determine the optimal number of CPO production, so that it can more effectively and ::: efficiently. Data on production, inventory and demand in 2014 as inputs. There are three steps to solve the problem using FIS Tsukamoto ::: i.e. Fuzzification, Inference and Defuzzification. The result obtained is the number of optimal inventory and production as well as higher ::: profit
