Hi Lok Thank you for your reply, it seems that your idea is very interesting but unfortunately, in my experiments it's impossible to realize because my piece of brass is a part of an experimental device and can't be removed. Thank you again for your idea

Thank you diazona for your reply. Actually I want to measure experimentally the thermal energy. So I think I will try to find a kind of oil which boiling temperature is higher than 300 °C. I should also think about how to pump this oil through the brass piece (I don't have now any pump). I used...

Thank you Drakkith for your answer. I liked very much " something somewhere" :smile: but seriously, the problem here is that the dimensions of my piece are not regular I only know its weight. I will try to look for this something :smile: Thank you again for your contribution

Thank you diazona for your interest. I will try to explain you what I mean by heating power: Let's consider that the temperature of my piece is equal to 50 °C. So there is an energy stored in this piece. If we circulate chilled water at 10 °C through the piece this water will come out at...

Dear all, I have a piece of brass material at high temperature (around 300 Celsius) and I would like to know how can I measure the heating power stored by this piece. the piece is designed in a way that we can flow a fluid through it. For low temperatures ( below 100 Celsius) it is maybe...

I found an interesting document about the process heating systems and I want to share with you if you are interested.http://www1.eere.energy.gov/industry/bestpractices/pdfs/process_heating_sourcebook2.pdf Regards

Thank you all for your contributions.

Thank you Vanadium 50 for your reply. In fact, I want to know the technologies used especially in the industries. In the food industry for example which method we use to increase the tempeature and what range of temperature is needed. In the oil refining also we need to increase its...

Dear All I would like to know what technologies are able to supply high temperatures (higher than 250 celsius) and in what fields these values of temperatures are needed. For example, I know that we use heat pump for water heating (around 80 celsius) or more simply we can obtain high...

Help pleasezzzzz

Hi everyone, I would like to simulate the flow inside a tube having one closed end and the other end is driven by a loud speaker. The speaker creates an oscillating pressure (and velocity) which will have an effect on the acoustic field inside the tube. so to be clear: which boundary...
