WebIf you want a controlled mass flow rate and high speeds, I'd use a two stage system. Start at high pressure P 1 and put the flow through choked nozzles to an intermediate pressure P 2 ahead of the nozzles that you've got. Then those nozzles will discharge to atmospheric pressure P 0 (or where ever they're discharging). WebAn optimal control strategy was tested to regulate the flow rate of the cold stream to maximize the time-averaged water production of a laboratory-scale membrane distillation (MD) process. The MD process is operated under fluctuating inlet hot temperatures at a fixed flow rate for the hot stream. The inlet hot temperature fluctuates due to fluctuation …
