ANSYS AIM 18.2 Extends Fluid Flow Simulation to More Real-world Applications

In ANSYS AIM 18.2, several improvements have been introduced to the capabilities for simulating fluids. In this blog, I’ll highlight two of what I think are the most significant.

First: time-dependent fluid flow (including solid-fluid heat transfer). Time-dependent fluid flow enables the modelling of both applied physics conditions that change over time, and unsteady flow phenomena, for example varying inlet velocity and/or temperature in an internal pipe flow simulation; or vortex shedding from external flow around a cylinder, such as a chimney.

Second: particle injection (also known as discrete phase modelling, or DPM for short), where the injected particle could be a droplet, for example, a fire sprinkler system spraying water into air, or raindrops, but it could also be a bubble of gas into a fluid. Continue reading
