ACU-T: 5100 Modeling of a Fan Component: Axial Fan
Prerequisites
This simulation provides instructions for running a steady state simulation of flow inside a pipe with an interior fan placed at the middle of the pipe. Prior to starting this tutorial, you should have already run through the introductory HyperWorks tutorial, ACU-T: 1000 HyperWorks UI Introduction, and have a basic understanding of AcuSolve and HyperMesh. To run this simulation, you will need access to a licensed version of HyperMesh and AcuSolve.
Prior to running through this tutorial, copy HyperMesh_tutorial_inputs.zip from <Altair_installation_directory>\hwcfdsolvers\acusolve\win64\model_files\tutorials\AcuSolve to a local directory. Extract ACU-T5100_AxialFanComponent.hm and AxialCoefficient.txt from HyperMesh_tutorial_inputs.zip.
Since the HyperMesh database (.hm file) contains meshed geometry, this tutorial does not include steps related to geometry import and mesh generation.
Problem Description
The problem to be solved in this tutorial is shown schematically in the figure below. It consists of an interior fan which rotates at a speed of 377 rad/sec (~3600 RPM) and has a thickness of 0.06 m and a tip radius of 0.11 m. The volumetric flow rate at the inlet is 0.146 m3/sec (~525.35 m3/hr). The problem is simulated as a steady state run and the pressure rise across the fan region is computed.
Open the HyperMesh Model Database
Set the General Simulation Parameters
Set the Boundary Conditions
Compute the Solution
In this step, you will launch AcuSolve directly from HyperMesh and compute the solution.
Run AcuSolve
Post-Process with AcuProbe
As the solution progresses, the AcuProbe window is launched automatically. AcuProbe can be used to monitor various variables over solution time.
Summary
In this tutorial you successfully learned how to set up and solve a simulation involving a fan component. You imported the meshed geometry and then assigned the material properties and boundary conditions to all the regions. Once the solution was computed, you defined a user function to create a plot of the pressure rise across the fan component volume.
