  INVESTIGATION OF GAS FLOW IN MICRO CHANNELS OF REFRIGERATION COMPRESSORS: MASS FLOW RATE AND MECHANISMS ACTING IN THE INTERACTIONS BETWEEN THE GAS AND THE SURFACE, Descrição: Gas flows in micro-systems are of great interest for various applications that touch almost every industrial field. This diversity is typified through the following examples: fluidic micro-actuators for active control of aerodynamic flows, vacuum generators for extracting biological samples, mass flow and temperature micro-sensors, pressure gauges, micro heat-exchangers for the cooling of electronic components or for chemical applications, micro-pumps and micro-systems for mixing or separation for local gas analysis, mass spectrometers, vacuum and dosing valves. The main characteristic of gas micro-flows is their rarefaction, the level of which often requires a modeling both by continuous and molecular approaches. The role played by the interaction between the gas and the wall becomes essential and it is generally badly known. Numerous models of boundary conditions are currently in confrontation and require an empirical adjustment strongly dependent on the micro manufacturing techniques. On the other hand, the experimental data are fragmentary and difficult to confront. Most of them do not address heat transfer and gas mixtures issues. The objective of this project is to structure research in the Federal University of Santa Catarina in the field of micro gas flows in order to improve global fundamental knowledge and enable technological applications to an industrial and commercial level. The main research area will be focused on the gas/surface interaction at a molecular level and gas flows in micro-devices. Keywords: molecular gas dynamics, rarefied gases, micro-fluidics. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Marcos Javier Rojas Cardenas - Coordenador / Cesar Deschamps - Integrante / Ernane Silva - Integrante.
