There are two basic bubbling regimes in direct-contact heat exchanger: homogeneous and heterogeneous. Industrially, however, the homogeneous bubbling regime is less likely to prevail, owing to the high gas flow rates employed.

CHAPTER 7 COMPARISON OF HEAT EXCHANGERS

But of the three, the counter flow heat exchanger design is the most efficient when comparing heat transfer rate per unit surface area. The efficiency of a counter flow heat exchanger is due to the fact that the average T between the two fluids over the length of the heat exchanger is maximized, therefore theCHAPTER 17 HEAT EXCHANGERS17.2 CHAPTER SEVENTEEN least one of the fluid sides, which usually has gas flow.
