Avaliação do uso de fluidodinâmica computacional (CFD) em spray dryers

Abstract

Computational Fluid Dynamics (CFD) is a simulation tool that uses computers with high processing capacity and applies mathematical models for the simulation of fluid flow patterns, making it possible to predict velocity, temperature and pressure profiles, among other specific parameters of the studied system. In this way, the objective of the work was to perform a bibliographic review on the application of CFD, moreover, to study the models used in simulations of spray dryers of CFD and select one the papers found during a literature review and try to reproduce the simulation makes (if) author(s). The CFD technique is widely used in automotive, aerospace and nuclear industries, but only in recent years has it become employed in the food industry. Its main advantage is the possibility of optimizing processes, generating cost savings and improving food quality. This tool has been heavily employed in studies investigating the effect of air flow in indoor spray dryers. In this way, to understand how the CFD modeling of the spray dryer is done, a paper of the literature was chosen, and from the data provided there was an attempt of simulation. The results of the simulation were promising, although it was not possible to reproduce all the profiles presented in the paper.
