Week 5.3 - Electronic Enclosure

CHALLENGE: To Model real fan behaviour using MRF modelling approach.   MODEL: 1. The model have been given as .tzr file and it was unpacked and visually inspected to define meshing approach. 2. The moving fluid zones necessary for the MRF modelling have been created over CAD models of blade geometry.   MESH:…

CHALLENGE: Build the model as per the following information. Mesh the model with nonconformal meshing Solve the problem for natural convection.   MODEL: 1. The model have been created based on given drawing. and simplified to ICEPAK objects using spaceclaim. 2. Two grilles have been created in the bottom with direction…

CHALLENGE: To create high quality mesh for given electronic cabinet model and to carryout natural convection simulation in steady state and transient state condition to validate the thermal perfromance of the electronics cabinet.   MODEL: 1. The model given is initially verified for simplification and all unnecessary…

CHALLENGE: SETTING UP CASE TO SOLVE FORCED CONVECTIVE HEAT TRANSFER IN ELECTRONICS CABINET.   CAD CLEAN UP: 1. The geometry have been visually analyzed to perform cad cleanup. insignificant components have been identified and removed. 2. Outer cover have been removed as it dont have important components and replaced…

CHALLENGE: To create workflow in Ansys Workbench and to simplify geometry for ICEPAK and create high quality Non-conformal mesh and solve it for forced convection case with 30CFM for fan. ICEPAK Geometry Cleanup: 1. Initially the electronics cabinet was examined for simplification, unnecessary components are removed. 2.…

Project statement: To inspect the elements with poor quality and mesh bleeding. and to improve mesh resolution. Techniques used: 1. MLM                           2. uniform mesh params                           3. cut cell meshing                           4. size region   Procedure: 1. Initial mesh was generated which…

Problem statement: Cold plate is used to remove heat from 2 parallel hot plates emitting 200W of energy. Project statement: To set up Transient simulation to validate characteristics of Temperature, flow in internal flow in cold plate and external flow characteristics due to natural convection surrounding cold plate and…

Project 3: To create a workflow in ansys workbench for Icepak project, and to convert a given electronics model to suitable Icepak model. Steps: 1. Model was imported to space claim and was visually inspected. unnecesaary regions in the sheetmetal cover was removed using split body option. 2. Bolts, nuts, washers which…
