    How to model Natural Convection model in ANSYS

    I have a thermal model of a rubber hose that houses a heat-generating device. There is a stagnent fluid inside the hose and around the heat generating device, and outer hose wall is held at a constant temperature. So far I have assumed only conductive heat transfer but in reality the fluid...

    Pro/Cable Tutorials?

    I'm looking for electronic tutorials on Pro/Cable. I havent been able to find anything useful on Google. I'm usually pretty good at figuring software out, but this is quite unintuitive. If anyone knows of any downloadable tutorials, please let me know. Many thanks in advance,

    In search of thermal properties...

    ISOPAR - L from Exxon Mobil Chemical. I can't find these anywhere - neither can Exxon Chemical. Exxon has various distributors but none of them have it either. My only hope is if someone else did tests. I need Cp and K values to do an honest analysis. If anyone knows anything, enlighten us...

    Friction / Damping Calc

    I just derived the formulas and that matches pretty close. Thanks

    Friction / Damping Calc

    I'm designing a spring with spring washers (belleville type). I'm looking for formulas to calculate the damping / frictional effects of stacking them unidirectionally. The stress / deflection formulas are easily found.

    What are the "must-have" resources (books, pdf) for a young engineer?

    Many thanks to everyone. I agree that good texts alone don't make a good engineer. Some of those I've heard of, some not. My next move is to do a little reading up on each book and possible drop some $$ off at amazon, half or ebay. It seems there is considerable cost difference in getting...

    best engineers pocket calculator

    I got the HP 49g, TI-36X Solar (for use on FE Exam), TI-83 and TI-85. While in school I kept finding calculators (TI). I purchased the 49g because you can use rpn or standard, whatever your flavor. For a pocket calculator, I'd recommend the TI-36X. It doesnt use batteries and the does the...

    What are the "must-have" resources (books, pdf) for a young engineer?

    I'm just starting out in design engineering. I'm looking for resources (books, pdf, websites, etc) for all the stuff they don't teach in school: 1. Manufacturing processes a. CNC and non-CNC b. Designing plastic / elastomer products and processes c. Design of Weldments d. Cost...

    air flow past a flat plate at some inclined angle

    I need to do a calc that involves an inclined plate at some arbitrary angle with fluid flow around it. More specifically, the plate pivots about an axis, and I'm looking to express the reaction moment (for steady state conditions) about its pivot axis as a function of inclined angle, fluid...

    pinned joint design

    A514, Thanks! I'm going from memory, but I think I derived shear stress = 4P/3A out of VQ/It for a round pin. Thanks everyone for your input.
