I thank everyone for their active participation in the topic. I try to reply to some observations:
I just need 1 psi, a liquid ring vacuum pump can do it and accept carryover.
There is no risk of the skin bursting if the product is not heated first. We usual peel other products at lower steam...
after pumping air, i'll put 15bar of steam in the first vessel. I have enough time, about 50 sec, to empty the buffer tank for vacuum. This is a machine to peel fruit and vegetables. I want to be sure that I don't have air that create a insulating barrier for product.
thanks for suggestion. What I'm interested in is speed and removing at least 70% of the air. Do you think that connecting the vacuum pump directly to the 400-liter tank would give me an advantage in terms of speed? Or would it be better to have an additional tank where I create the vacuum in...
thanks for help, I supposed to have a vacuum tank of 800 l with 65cmHg pressure. After valve opening, the vacuum in the full system of 800l+400l should be 43cmHg. I used Boyle-Mariotte for this calc.
Hello everyone, I need some advice on how to quickly remove air from a 400-liter tank before performing a thermal process. I was thinking of creating a separate tank where I can create a vacuum using a pump, and then use an automatic valve to connect the two tanks. My question is: how do I...
thanks for the quick response Goutam; i don't understand why i can't provide flow and pressure at the inlet as it is normally done. They should be indipendent parameters, or am I missing something? Maybe you mean velocity+ pressure or velocity+steam flow as the couple of inlet BC?
Hi to all, I would like to simulate in cfd (ansys discovery live) a steam pipe distributor, but i have difficulty to set boundary conditions. This pipe connect a control steam valve with a pressurized tank.
I know pressure of steam feed and mass flow; i want to calculate mass flow, velocity and...
