From previous studies [30-33], it is well known that the characteristics of flow around an airfoil at low Reynolds numbers
are considerably different from those at moderate and high Reynolds numbers
The equilibrium position of the particle [Y.sub.eq], which is the vertical position of the particle to the width of the channel, at different Reynolds numbers
(Re = 20, 40, 60, 80, 100, 120, 160, 180, and 200) is shown in Figure 2.

Figures 12(a) and 12(b) show the relation of the TEF with the flow attack angle at various Reynolds numbers
for the square channel heat exchanger inserted with wavy plates for V-Downstream and V-Upstream, respectively.
Here is some explanation of the changing conditions as flow rate and Reynolds numbers

Later on, it has been observed during the analysis that the first dimensionless number [[PI].sub.1] is the Reynolds number
measured during flutter and then called flutter Reynolds number
The horizontal flow demonstrated an increasing linear trend as the main flow rate was also increasing (see Figure 2) whereas the ratio of the horizontal flow rate appeared to maintain the linear trend and did not significantly change when the Reynolds number
was increasing (see Figure 4).
Results have shown that at certain Reynolds numbers
(Re = 10 or 40 < Re [less than or equal to] 100) the left particle always sediments at 0.175 of the channel width irrespective of its initial position or the channel width.
Therefore, falling film remains stable even for the very small flow rate (liquid Reynolds number
smaller than 1).
As shown in Figure 9(b), when the Kc number increases, the vertex of the curve approaches low Reynolds numbers
. In the range of 5.5 to 6.7, the gradients of the curves are similar.
