I have been trying to figure this out for a while and am having a problem with putting this together. Here is the setup. I have a long square hollow beam (L=2m, h=w=0.3m, t(wall)=0.5in), capped of on both side with the same thickness plates. Its loaded in compression as well as there is a...
I am not sure if this is even possible, but if so it would definitely be of use to me. I have spent some time looking into ways of measuring (in situ) surface roughness (Ra) of a rotating Cu disk, to determine changes in surface roughness with time, while is it being abraded. Since this...
I am not sure if I am in the right forum for this question, but I have been looking around for this for quite some time and can not find it anywhere.
I am in search for a small DC liquid (water) pump (12-24V DC) that will be able to operate at ambient temperature but with water @ 25-90 deg C...
I have the following problem and would appreciate any input on the subject. I have a recirculating (low preassure) CO2 system, driven by a blower, and at one point am adding steam through a nozle into the main tube (d = 2.5in). I am using a small (2kW) steam (sauna) generator. At this point...
I have worked out a thermal model to predict steady state (SS) temperature distribution for a TEFC machine based on already existing models created for example by P.H.Mellor. I would like to estimate the transient response, or at least the max winding temperature under a higher transient load...
I am aware that this is a very broad question, but was wondering if there is an approximate method to evaluating a needed radiator size? For example, lets take a 200hp, turbocharged engine, 1.8L, 4cyl motor. I know there are lots of variables in this problem such as the coolant flow rate, air...
As the questions states, was is a typical coolant flow rate and radiator output temperature for a small displacement engine. In particular I am in need for numbers relating a small 1.6L 4 cylinder engine like a Honda Civic, and a hayabusa 1300cc engine. Any info would be greatly appreciated...
I was wondering if there is a known way of predicting the natural convection coefficient for radial fins. Basically, I have 960 thin copper fins (t=0.13mm, fin pitch = 1.3mm), louvered, and are attached to a cylinder of diameter 210mm. From various sources, empirical data gives me the h value...
I am working on a heat transfer problem, and need a good estimation of predicting the conduction coefficient for some type of adhesive tape that is used to attach thin,cooper fin strip to an aluminum case. All I know about it is that it is green, crumbles if I try to take it off (probably...
I have spent some time searching this issue and can't seem to locate any source with good information on copper multilouver fins. One layer of these fins is attached on the outside to an aluminum cylinder that is internally heated. I am trying to calculate the fin performace, convective...
I have a 200 hp. 12000 rpm AC induction motor, and would like to raise its power output. It is currently being air cooled from the outside by a fan blowing air through fins attached to the outside of the motor casing, the stator. My main question is where most of the heat is generated? Is it...
