I want to write my thesis for master course and i need some suggestions to increase the efficiency of plate heat exchanger.
Plate heat exchangers are often used when the cooling fluid isn't clean because a plate heat exchanger can be dismantled and cleaned fairly easily, much more so than one that requires cutting and welding. Several things have been tried, including: rinsing, periodically reversing the flow, pulsing the flow, and introducing abrasive particles. What about acoustic stimulation to discourage accumulation of stuff on the surface; that is, keep the crud suspended and perhaps filter it out. You could also consider rather than a filter, running part of the stream through a centrifugal device to remove sludge without interrupting service. Go out and see some of these in action. One place you will find plate heat exchangers is a stationary combustion gas turbine. I've seen a variety of these at power plants. Get someone to take you on a *real* tour of a plant--not the "visitors" tour but the "maintenance" tour.
I suggest you to read some recent review articles on plate heat exchanger technology, as in most of review papers, authors highlight the research gap in the field. From there, you can get some ideas for your thesis writing.
Wish you best of luck!
Plate type of heat exchanger is for cooling and heating only, it not use for evaporation and condensation.
