3D Supersonic Flow in a Channel With a Bump

This example models 3D supersonic flow, including the effect of a shock, in a straight channel with a small obstacle on one of the walls. As the flow hits the obstacle, shock waves are diffracted from the obstacle and walls of the channel. The propagating shock waves form a pattern in the velocity profile and density distribution. The model makes use of the adaptive mesh refinement feature in ...

Flow in a Hydrocyclone

Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2-f turbulence model is used to simulate the flow in a hydrocyclone. The v2-f turbulence model, which is an extension of the k-ε turbulence model, provides highly ...

Thermophoresis

When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the cold side, which results in a net force towards cold areas. This effect can be exploited to create thermal ...

Transient Elastohydrodynamic Squeeze-Film Interaction

This benchmark model computes the transient pressure distribution and film height in a squeeze film bearing for lubrication in a nonconformal conjunction of a solid sphere and an elastic wall separated by a lubricant film. This model solves the benchmark case of hydrodynamic interaction between a solid sphere and a wall separated by a lubricant film, and extends the benchmark case to include ...

Displacement Ventilation

In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic devices, or inlet jets of warm air. A potential issue with the displacement ventilation approach is that ...

Turbulent Mixing of a Trace Species

This tutorial model demonstrates how mixing can be visualized in a stirred vessel by seeding a trace species from a point. The flow is modeled using the Rotating Machinery, Fluid Flow physics which solves Navier-Stokes equations on geometries with rotating parts, for example impellers. The transport of the trace species is modeled using the Transport of Diluted Species physics.

Transonic Flow in a Sajben Diffuser

In this model the high speed turbulent gas flow in a converging and diverging nozzle is modeled using the High Mach Number Flow interface. The diffuser is transonic in the sense that the flow at the inlet is subsonic, but due to the contraction and the low outlet pressure, the flow accelerates and becomes sonic (Ma = 1) in the throat of the nozzle. After a short region of supersonic flow, a ...

Natural convection in a closed cavity with mass conservation

Only fully compressible flow can guarantee the mass conservation in time in a closed cavity where the temperature increases. This is a simple proof of concept using the "gravity" option available in V5.2A.

Journal Bearing with Cavitation

A journal bearing is composed of an outer cylinder (bearing) wrapped around an inner rotating journal (shaft), with a lubricant separating the two. Under certain operating conditions, cavitation can occur between the bearing and the journal, leading to component damage and failure. Knowing the rate of cavitation is helpful when determining the maximum applied load. Cavitation occurs when the ...

Coriolis Flow Meter: FSI Simulation in the Frequency Domain

A Coriolis flow meter, also known as a mass flow meter or an inertial flow meter, is used to measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, the density and thereby the volumetric flow rate can also be assessed using the device. This ...
