Numerical Investigation of Micronozzle Performance for Various Nozzle Geometries
Design and manufacture of thrusters for producing very low thrust force in the range of milli or micro newtons using micronozzles has been actively developed in the last decade. The nature of propellant flow in such micronozzles differs from that of macro nozzles. In micronozzles, ... Read More
Análise da Aproximação para Baixa Absorção Óptica na Geração de Calor Via Laser em Sólidos Semitransparentes: Aplicação na Técnica de Lente Térmica
Neste trabalho utilizamos o software COMSOL Multiphysics® para resolver a equação de difusão de calor induzida por laser. Está equação é a base de técnicas fototérmicas em especial a técnica de Lente Térmica. Além de resolver a equação de difusão sem o uso das aproximações de amostra ... Read More
Using Computational Fluid-Dynamics (CFD) for the Evaluation of Tomato Puree Pasteurization: Effect of Orientation of Bottle
Determination of the temperature in liquid foods may be derived by measurements or by modeling. However, the placement of thermocouple probes to record temperature in the container disturbs the flow patterns. For this purpose, Computational fluid-dynamics (CFD) offers a powerful tool for ...

3D Analysis of Cavitation in Control Valve by Pressure Variation
The phenomenon of cavitation can severely affect the working of valves used to control liquid flow. Cavitation occurs when the pressure is reduced and the water evaporates, forming bubbles. When bubbles pass into an area of higher pressure, they condense and collapse, releasing a large ... Read More
Residence Time Distribution for Tubular Reactors
In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal ... Read More
Simulation of a Piezoelectric Loudspeaker for Hearing Aids and Experimental Validation
The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost. However, the performance of such systems is still not competitive when compared ... Read More
Numerical Simulation of the Heat, Mass, and Momentum Transfer During the Microwave Drying of Osmodehydrated Porous Material
Recent studies have been devoted to develop mathematical models to simulate the food processing using the porous media approach. The aim of this study is to simulate the microwave drying of osmodehydrated food by means of modeling the mass, energy and momentum transfer using the porous ... Read More
Analysis and Development of Koch Fractal Dipole Antennas
Devices of mobile communication require smallest sizes of antennas. This is one of the applications of fractal antennas which have reduced size or are multiband and can be used for mobile phone, RFID, Wi-Fi, digital TV, among other applications. The Koch fractal geometry allows better ... Read More
Understanding Logging-While-Drilling Transducers with COMSOL Multiphysics® Software
Logging-while-drilling (LWD) acoustic transducers provide real-time data about the geologic and geophysical properties of the borehole that ensure safety margins and optimize completion. It is important to understand what causes the different resonance modes in the transmitter and obtain ... Read More
Fluid Dynamics Analysis of Gas Stream in a Plasma Torch Reactor
Plasma technology has potential applications in a wide range of areas, such as microwave reflectors/absorbers, material processing, sterilization and chemical neutralization. The knowledge about the fluid behavior in such systems has a central role, since the stability of the flow in the ... Read More
