This is my understanding so far. I can cool an object, the equation dT/dt=kA(Tplate-Tair) can be integrated and I can see what happens when the heat is turned off, and there is only cooling of the air. But what happens when I turn the energy back on. I know that qcond=Q/t, where...

Sorry, I'm probably doing a poor job of describing it. I'm going to assume the temperature of air stays the same, so Tair=80F for example. if the plate has a surface area of 2ft^2, and a mass of 35lbs, and other constants, what would the temperature of the plate be if given a heat flow of...

Would there be a good way to find the Temperature at time=t?

I'm not sure what the Mayan web page is?

I have yet to find anything on this topic, and while I have another post going, this one I want to keep simple: If 4000 watts is applied to a plate, of volume V and Area A, in a steady state temperature of T, how hot can it get, and over what period of time?

I am going to start from scratch on this one now. Just to start, I want to see how hot my plate can get with constant energy. If 4000 watts is applied to a plate, of volume V and Area A, in a steady state temperature of T, how hot can it get, and over what period of time?

What is going on is we have a design already in place in the plant. Its basically a large plate with a set of heater cartridges inside. We have problems keeping the temperature steady when trying to run the line. I am changing what I originally wanted to see. What I am curious of is how fast...

Thanks for the comments, those were parameters I was thinking of using but I am just not sure how to use them. Would there be a way to determine how much energy is used when melting the plastic, and how much the temperature of the plates drops? I know the cycle time of the machine, and it...

I was hoping to model the response under a number of different parameters. Such as, how well does it respond to when it is larger, more surface area. Or if the temperature of the air is different. it is more of an excersise of designing it and modeling the system before we build it so we have...

I have a heat plate that is used basically to melt plastic, and I need it kept at a relatively constant temperature, so the surface temperature is what I need. It isn't really steady state. It is like an oven, energy is supplied until a set temperature is reached, then turned off to a set...

I am trying to model a system and so far haven't been able to do exactly what I want. I have a plate, heated by electric heater cartridges, about 4000 watts total. For now I will assume the surface temperature is the same as the internal temperature, unless anyone knows of a good way to do...

I have created a beam using Pro Engineer. My question is probably simple and basic, but I am just starting on the software and haven't figured it out. I imported the beam into ANSYS as a step file. I applied the load correctly, however I am not sure how to apply a fixed support. The support...

I am modeling a heater platen for an assembly process. I am using several heater cartridges that will be inserted into the center of the platen. My question is pretty simple. I know what the wattage of the heater cores will be. How would I go about modeling the entire process so I can find...
