CFD simulation for thermal efficiency calculation

$15-25 USD / hour

$15-25 USD / hour

We have an existing mathematical model of a proposed aluminum heat sink under forced ventilation for a consumer electronics application. All relevant parameters are characterized and a 3D model is available (.skp or Collada). The initial design is very simple and straight forward. We require thermal simulation under normal and extreme operating conditions to determine thermal power flow (source-to-air) or equivalent thermal resistance/conductance. Further, we will require additional simulations with altered physical designs (for example with different fin profiles, different dimensions etc.) for possible improved efficiency. It is assumed that some of the cases will include turbulent flows. The exact number of simulation iterations are not yet known, however the simulations can be grouped to allow for interim/progress payments and work packages will be discussed and agreed beforehand in terms of expected time requirements.

Hello, a very interesting project for me. Because I myself work in the laboratory of thermal physics and we are engaged in the calculation and modeling of heat fluxes, heat transfer coefficients, etc. Look, please, for examples of my past works in the portfolio that are related to CFD. If I need to sign NDA then for me it is not a problem. Write to me it will be interesting to talk.

Hello, I am a CFD expert with mechanical and chemical engineering background. I have done many CFD projects using Fluent, COMSOL, Solidworks, and AutoCAD in the past 10 years. Here are some projects I have worked on: - Simulated compressible/incompressible turbulent flows (k-e, k-omega, LES) in various geometries (2D,3D) such as airfoils, orifice and venturi - HVAC modeling of a hospital room in Solidworks, conference room in Autodesk CFD - Thermal analysis of a breaking pad and air cooling the pad for longer lifetime - Simulated cavitation in pumps and ship impellers - Simulated particle concentration in mixing cell - Simulated flow through cracks and nozzles in oil pipelines - Simulated thermal comfort in a room with a temperature controlled heater - Simulated slurry and bubbly flows in pipes - Simulated heat transfer and reactions in packed bed reactor - Used UDF programming to add a new feature such as specified velocity inlet, DPM particles interactions, ... Also, my Ph.D. thesis was about the design and optimization of a device to produce cavitation in venturi and orifice using ANSYS-Fluent. If interested please contact me to talk in more detail about your project and define our milestones. I Look forward to hearing from you. Regards Shaham

Dear Buyer, I have reviewed you request for proposal. Based on my study you require CFD analysis of the model given in the figure as attachment. I would appreciate if you could provide me with further details so that I could look into it and come up with detailed analysis of the project so that you could have the clear vision for the project. If you require something similar to this then please provide us with further information to carry out design, so that we could discuss the same in our further meet. Regards Paramjeet Singh

To complete this analysis necessary things required is the what kind of condtions it is exposed to it. Analysis is to be done on the time based analysis or steady state based analysis. also simulation will be carried out on the simulation software named ANSYS FLUENT. and I assure that i will provide sufficient data with accurate sollution.
