A novel pressure sensor is investigated numerically. Operation of this sensor is determined by mechanical stresses and heat exchange. Estimation of deformations and heat transfer was done using programs ANSYS and ANSYS CFX. Numerical model was calibrated to fit experimental results. Conclusions about significance of heat exchange, thermal stresses and overall action of sensor were made. 1. Gene...

purpose: in recent years high explosive bomb attacks have been increasingly directed against   civil structures by various terrorist organizations. this paper describes a numerical method for   assessing the interaction of high explosive air blast within the complex geometrical type of a   congested urban environment.   materials and methods: the first step in predicting blast effects on a targ...

An experimental and numerical investigation into the tip leakage flow of a turbine rotor is carried out using a particle image velocimetry (PIV) system and the commercial software ANSYS CFX 14.0. The specimen used in this work is a typical GE-E3 model with a new squealer tip design. The experimental data are used to create a turbulence model and numerical strategy. Through the validated turbule...

Abstract. Numerical investigations of fluid structure interaction between unsteady flow and vibrating liner in a combustion chamber are undertaken. The computational study consist of two approaches. Firstly, a partioned procedure consists of coupling the LES code AVBP for combustion modelling with the FEM code CaluliX for structural dynamic analysis. The CFD code CFX together with the FEM Ansys...

This work presents an analysis about microreactors of different geometries for the biodiesel synthesis. The microreactors were made by a polymeric substrate with the photolithography technique. Simulations were made using the computational fluid dynamics software ANSYS-CFX. They show the flow behavior through the microchannels. Experiments were performed to produce biodiesel, with syringe pumps...

This work was one of the tasks of the Manufacturing2Client project, whose objective was to develop a frontal deflector to be commercialized in the automotive industry, using new project and manufacturing methods. In this task, in particular, it was proposed to develop the ability to predict computationally the aerodynamic influence of flow in vehicles, in an effort to reduce fuel consumption in...

Pressure distributions over a 20° conical forebody are computed by the commercial CFD software ANSYS CFX. Free stream velocity is 30 m/s, Reynolds number based on the forebody base diameter is 0.3×10 6 , and the angle of attack ranges from 10° to 35°. The C-O structural grids are used to compute the entire flow field. The governing equations are steady Reynolds-Averaged Navier-Stokes Equations ...

The high-speed dental air-turbine handpieces are widely used in the dentistry as a tool for cutting and drilling a tooth. The advanced existing high-speed dental air-turbine handpieces were investigated to design the high performance dental air-turbine handpiece. The coupler and air-turbine of the dental air-turbine handpiece was designed using computational analysis. The computational domain o...
