The use of tensor calculus to explain & explore the governing equations of physics & mechanics is a very useful concept. In my view, this is the backbone of Continuum Mechanics.

^^ Excellent review ShawnD - thanks.

I'd love to run a few micro-channel cfd simulations on that beast.

Glad to hear that you're around to tell the tale. A severe electric shock is a horrific experience.

The heat load is the amount of heat you want to extract from a particular space e.g. room, over a certain time. In other words rate of heat-extraction in Watts (typically kW, or Btu/h). This occurs on the evaporator in a domestic hvac system. The sink is where the heat load, extracted from the...

The maximum achievable capacity of the HVAC&R system as a whole, based on initial set-up conditions, charge volume & so forth - would be affected if the load & sink values were changed. Most domestic hvac's have a rated capacity before they are installed. The technician then comes along...

Do you have a complete working HVAC system available for your test? In other words, could you make a test chamber for the system & test it's capacity under controlled conditions? If that's the case, then you could read up on how companies test HVAC systems. Testing each heat-transfer...

Plucker_08, if this is an industrial application, then I'd suggest that you employ the services of a professional consultant. If this a student project, then you will have a lot of reading to do. These are simple facts of life. Some consultants have spent years researching & applying the...

The surges were possibly from air compressibility, with an inadequate drain venting system, plus a huge rain-storm.

^ Well, it was that way around 5 years back. This is what I was informed during a number of research visits I made to Dortmund University, for instance. I never made use of the kindness. It could well have changed in the meantime. You would probably have to have some sort of prior arrangement...

Germany. If you learn to speak German - free 6-month course - you pay no academic fees.

I'd agree with Oerg. Whatever you do, don't think of going to Thailand. Their universities are not as good as they'd like to claim. Basically, this is really down to inexperience & attitude towards learning - as well as an intrinsic anti-foreign sentiment (racism). Most of their so-called...

Heat transfer design of basic heat-exchangers, can be learned by reading a number of basic heat-transfer books. Evaporator & condenser design will require you to read a fair amount on the physical mechanisms involved. Try Collier & Thome, 'Convection boiling & condensation'. You could also try...

Wave phenomena are predicted. Thankfully, at this point, they look to be linear (if gamma & c are constant). If so, then you may be reasonably safe in using simple numeric strategies.
