In order to improve material flow behavior during friction stir welding and avoid root flaws of weld, a tool with a half-screw pin and a tool with a tapered-flute pin are suggested. The effect of flute geometry in tool pins on material flow velocity is investigated by the software ANSYS FLUENT. Numerical simulation results show that high material flow velocity appears near the rotational tool a...

This paper addresses the challenge of solution verification and accuracy assessment for computing complex Partial Differential Equation (PDE) model. Our main target applications are bio-heat transfer and blood flow simulation problems. However our long term goal is to provide a postprocessing package that can be attached to any existing numerical simulation package, for example widely used comm...

In the study, a numerical simulation of sliding properties rough and smooth surfaces with micro-structure was made. The shear flow in micro-channel performed ANSYS FLUENT software. 3-D two-phase is simulated by choosing volume fluid model. CFD analysis, water air consist two immiscible phases. calculations, if first second fluid, adjustments are At beginning channel considered to be completely ...

This paper presents a 3D numerical study of the bubble generation process in a T-junction, performed with the commercial Computational Fluid Dynamics solver ANSYS Fluent v15.0.7. Numerical results on bubble generation frequency, bubble velocity, volume void fraction, bubble volume, and characteristics bubble lengths are compared with experimental data. Additionally, a new simple tting for the b...

In the process of oil exploitation, subseatrees sometimes vibrate. this paper, fluid–structure coupling software was used to study causes subsea tree vibration. First, complex model simplified, and ageometric grid established for calculation. Then, under given two working conditions, Fluent analyze pressure velocity distribution pipeline’s flow field. It found that field changed greatly at vari...

This study proposed a the new cost effective design of diesel exhaust waste heat recovery system (WHRS) for Bus rapid transport System (BRTS, Jaipur) and Stationary System and proposes a cost effective robust design that meets the principle design constraints for WHRS. In order to address various design constraints for WHRS while achieving the required performance of the system, numerical analy...

Abstract The aim of the work was to create a CFD model flow generated around drone estimate impact field parameters on results actual measurements from PM sensors that are positioned differently in relation propellers. created with use ANSYS Fluent software allowed one determine criterion their sufficient distance. robots four, six and eight rotors were analyzed. For these, turbulence intensity...
