Triggering turbulence hence requires not only a sufficiently high Reynolds number
but also a perturbation of sufficient amplitude.
As the base-fluid Reynolds number
increases, the increase in the local Nusselt number can be observed in the vicinity of the rear stagnation point (Fig.
202 ft/s), corresponding to Reynolds numbers
based on channel height of 340, 570, and 940, respectively.
The Reynolds number
Re was assigned as the constant through all calculations and set equal to 4.
1975, Pulsatile blood flow in a channel of small exponential divergence-I: The linear approximation for low Reynolds number
For small Prandtl numbers, the logarithmic part of the temperature profile appears only at high Reynolds numbers
(Re > [10.
16 shows the pressure distribution curve on the suction surface of these two airfoils when the Reynolds number
is 350,000 and angle of incidence is 18[degrees].
The convection coefficient of heat transfer or Nusselt number is a function of both Reynolds number
and Prandtle number.
In the laminar region of Reynolds number
investigated, the measured local Nusselt numbers agreed with classical developing flow theory.
The procedure is suitable for analysis of low Reynolds number
airfoil flows with transitional separation bubbles.
Figure 6 presents the effects of the Reynolds number
on the mixing curves at constant eccentricity (E = 34.
High Reynolds number
and high Peclet number boundary layers are also covered.
