    Fan CFM Computation

    Thanks again for the answers guys. I am now considering the replies you've given and need some help on the computations of Heat transfer. Idea now is to compute the Air GAP so that the Heat (30watts) or Temperature (60C)entering the Housing is Less (*shown on the Sketch) I was trying to use...

    Fan CFM Computation

    Thanks Guys for the replies These are enlightening. I'd like to share a similar product in the Market that is currently working. This is the June Life Oven which has internal camera attached to the wall (internal oven temp reaches 500F) What we want is to somehow use that approach. Yes, there...

    Thermal Flow in Ceramic Material

    Yes, there are several modes but I will like to concentrate more on the Convection (sorry, not Conduction) at this time. Will it be Fourier's law or another Heat Transfer equation? I need it to be transient so time is essential to determine the temperature Can you advise on how to get the right...

    Thermal Flow in Ceramic Material

    Hello there fellow Eng-tips people, I am doing design of Ceramic Housing that is exposed to Conduction (Oven Grill). I need some help on how to compute the inner temperature and time before the inner surface reaches the same temperature as its outer wall Reason is, I want to get the...

    High Temperature Polymer that is FDA/USDA Approve

    Thanks Guys, I am now inclined on using Ceramic material (alumina) Any advise what type is recommended for an FDA/USDA approved material? Also, do you have ideas (filler or additives) on how to strengthen this so as to pass drop test.
