1. Investigação experimental e analítica do escoamento ao redor de cilindro circular com supressores de VIV. / Experimental and analytical investigation of the flow around circular cylinder with VIV suppressors.
The fluid flow around bluff bodies is one of the main problems in fluid mechanics. The investigations of this phenomenon are based on analytical, numerical and experimental techniques. Each technique presents advantages and disadvantages, being impossible the comprehensive characterization of the flow though only one technique for the majority of body geomet

2. Novo sensor de vazão de fluidos com foco em aplicações biomedicas / New fluid flow sensor aimed at biomedical applications
Spirometer is a device that evaluates pulmonary ventilation. This paper presents a preliminary study of a new electromechanical sensor, focused on the biomedical application of spirometry. The sensor is composed of a bluff body positioned inside a tube trough a hole, being a part of the body inside and another part outside of the tube, and an accelerometer p

4. Numerical simulation of two-dimensional complex flows around bluff bodies using the immersed boundary method
This paper presents a two-dimensional numerical simulation of flows around different bluff bodies, at Re = 100 and 200, using the Immersed Boundary (IB) method, as a sequence of a previous work. The force density term required by the IB method is obtained with the Virtual Physical Model (VPM). Simulations were carried out for two circular cylinders of differ

5. On contribution of advanced vortex element methods toward virtual reality of unsteady vortical flows in the new generation of CFD
The purpose of this paper is to explain the attractive applicability of the advanced vortex element methods and their contribution to the beginning of the new generation of CFD, with introduction of epoch-making application of the methods to simulation of unsteady flows around bluff bodies and virtual operation of fluid machinery. The vortex methods have bee
