WebThe countercurrent flow is opposed by interfacial friction between the phases, which always seems to increase monotonically as the relative countercurrent mean velocity of the phases increases. Hence, for a given geometry and liquid-gas pair, there is a maximum relative velocity that can be sustained in countercurrent flow. WebThe counter-current flow of the blood and dialysate maximizes the concentration gradient of solutes between the blood and dialysate, which helps to remove more urea and creatinine …

The reason for their motion "counter" (opposite) to the wind flow is because the northern and southern equatorial currents, pushed westward by the trade winds, pile up water in the western portion of each ocean basin. This results in a sea surface is about 0.5 meter (18 inches) higher in the western Pacific ...

WebIn this paper, four arrangements of three-fluid cross-flow heat exchanger (3FCFHX) with different flow conditions are considered as shown in Figure 1 in which is the performance of cross-countercurrent and cross-cocurrent arrangements for uniform and flow maldistribution at the inlet. WebThe countercurrent flow of blood through the lamellae in relation to external water flow has much to do with the efficiency of gas exchange. Laboratory experiments in which the …
WebWhy is counter current flow better? One of the great advantages of counter-current flow is the possibility of extracting a higher proportion of the heat content of the heating fluid. It is important to note that the LMTD value for counter-current flow is much larger than for cocurrent flow at the same terminal temperature (see Figure 1.9).
