... transfer not only by enlarging the fluid contact area but also by destabilizing the flow field. The flow instability caused by the baffles triggers laminar-turbulent transition. Consequently, mixing is greatly increased in the disturbed flow field, resulting in more effective heat transfer [( 1 2 3 4 5...
