Week 4 - CHT Analysis on Exhaust port

Aim: To perform a steady state conjugate heat transfer analysis on a model of graphics card. By defining solid and fluid materials accordingly.  Introduction: Given model is Graphics card which includes Processor, Fins, & base body.  Out of these parts Processor is the heat generating part which need to be cooled down…

CFD Model based on Rayleigh taylor waves: Kelvin-Helmholtz instability. Richtmyer-Meshkov instability. Plateau-Rayleigh instability. Kelvin-Helmholtz instability: This kind of instability or transition to turbulant flow happens between fluids of different densities moving at different speeds. in such case a wave formation…

Aim:  To simmulate conjugate heat transfer concept using a exhaust port of an engine. and to understand how heat convection happens around the wall of exhaust pipe. Introduction: Given model is a exhaust pipe of a four cylinder engine. we are here by instructed to conduct a hot fluid flow simulation in particular given…

AIM: To conduct air flow simulation over a ahmed body inside a wind tunnel to understand the real life applications of vehicle. To understand about wake region, to understand about wake region. IMPORTANCE OF AHMED BODY: Ahmed body is perfect model to understand the basic concept of air flow, wake region formation, point…

                                                                                                                  FLOW OVER A CYLINDER AIM: To simulate flow over a cylinder under both steady and unsteady conditions. considering various reynolds number ie., 10,100,1000,10000. also to get, drag, lift & stroural number. PART…

Aim to find out effective mixing velocity, suitable model  and avg temperature at the oulet. And also to obtain plots for standard deviation,…

Aim: To check and solve all geometric errors and assigning proper PID's, performing 2d mesh, and also creating a tunnel to perform vol. mesh. considered 2mm as target length. Procedure:  Checking the given model for geometric errors and clearing the same. filling all missing elements. After topology cleanup &…

AIM: For the given model checking for geometrical errors, deleting unwanted surafces which are not needed & after clean up merging all 3 models. Also performing surface wrap for merged model with target length of 3mm. Procedure: Importing the given model and deleting all unwanted  surfaces which looks unnesessary for that…

AIM: For the given model, to check and solve all geometrical errors on half portion and Assign appropriate PIDs. Perform meshing with the given Target length and element Quality criteria. dublicate the same to other half also, creating a air tunnel around the model and isolate the required volume and generating volumetric…

AIM: To clean topology of given turbo charger model, mesh it in 2D and then proceeding for volumetric meshing. Procedure: After importing model of turbo charger found many single coons and missing surfaces. Solved for missing surfaces and created new surfaces wherever required. used multiproject, intersections, parametric…

AIM: To mesh given model. with element type : tria  1mm, 3mm & 5mm. Procedure: Importing model. Performing geometry checks and finding single cons, cracks etc. Creating new faces to clear all single cons.  checking for geometry again. found ok. Using cut option clearing all small segments to avoid problem…
