The paper presents the results of experimental and model tests transport dispersed fluid droplets forming a cloud aerosol in stream air ventilating selected section underground excavation. excavation for testing is part ventilation network Experimental Mine Barbara Central Mining Institute. For given environmental conditions, such as temperature, pressure, relative humidity, velocity air, distr...
This paper considers the problem of predicting the technical and operating characteristics of the propulsion system of a microsatellite created by microelectronic technology. The coupled thermomechanical problem of hydrodynamics has been solved by the ANSYS CFX package. The microengine design has been optimized, the heating of its case in the operating time of the fuel chamber has been analyzed...
Water impact phenomenon of general bow section is a critical event for planning hulls. In this paper, the water entry of several arbitrary bow sections is investigated. For this purpose, arbitrary bow shapes which are introduced by Lewis form approximation are considered. In order to obtain pressure distribution and free surface profile, volume of fluid (VOF) method coupled with finite volume m...
Three different test cases involving free surface flows with surface tension were investigated with ANSYS CFX. Transient analyses were performed in all cases. The three cases were: (1) oscillations of a twodimensional cylindrical rod; (2) rise of liquid in a capillary; and (3) rise of an air bubble train through stagnant water. The mesh resolution, timestep, and solver settings required to obta...
The Inject Pipe Mixer (IPM) are being used as venturi injectors and can also homogenize two fluids. The entry of secondary fluid as a jet influences flow field in the device. A CFD simulation of flow through an IPM (Lshape) has been carried out using ANSYS CFX 11.0 using water as the flowing fluid to understand the flow field under turbulent flow conditions using standard k--ε model. The result...
Abstract The article presents a technique for process-induced residual strain modeling thermoset composite material parts. model takes into account the mechanical and thermal contact between part mold. is implemented in ABAQUS software using user subroutines. Using technique, it possible to clarify distribution of heat transfer coefficient on surface mold CFD method. Distribution coefficients a...
The simplest water diversion method in irrigation systems is using intakes. Measuring the mean velocity is one of the essential hydraulic parameters in increasing the efficiency of the intake. In this study, the mean velocity was predicted for different width ratios of an intake using ANN-MLP neural network model. In order to do that, the flow field within a 90-degree intake was first simulated...
Many patents have suggested that spinning the aircraft wheel before touchdown would lessen tyre wear as indicated by landing smoke and rubber deposites on the runway caused by skidding wheel at the point of impact. In this paper, the required torque to spin the aircraft wheel at approach speed has been calculated using ANSYS Workbench CFX, which is used to determine the wheel aerodynamic forces...
