In this study, liquid-liquid extraction process in a Kuhni extraction column was modeled and simulated. A non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. The model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. The population balance model was used ...

ecological changes resulting from climate conditions can severely affect human societies especially in the area of economy and safety. climate catastrophes may cause social and economic tension. forecasting such changes accurately can help the government to control the disasters and to achieve possible benefits (such as water supply in flood). weather forecasting is the application of science a...

This paper presents a detailed model of common rail diesel injector and its validation using injection rate measurement. A new method is described for nozzle flowrate determination simulation measurement tools. The contains fluid dynamic, mechanic electro-magnetic systems, describing all-important internal processes also includes the meter model. Injection measurements were made Bosch method, b...

one may find out the application‎ ‎of mathematics in the areas of ecology‎, ‎biology‎, ‎environmental‎ ‎sciences etc‎. ‎mathematics is particulary used in the problem of‎ ‎predator-prey known as lotka-volterra predator-prey equations.‎ ‎indeed‎, ‎differential equations is employed very much in many areas‎ ‎of other sciences‎. ‎however‎, ‎most of natural problems involve some‎ ‎unknown functions...

This article proposes an agent-based model to study the impact of the European regulation REACH on industrial dynamics. This new regulation was adopted in 2006 and establishes a new philosophy of how to design environmental protection and health, especially through the authorization process and the extended producer responsibility. The main contribution of this article is to investigate how dif...
