3) At Reynolds number
1190, the dye trace shows the start of transition to turbulent flow but there remains a sheath of laminar flow around the turbulent center.
13] investigated the effect of aiding/opposing buoyancy on the turbulent flow field and heat transfer across a square cylinder in vertical channel, the level of wall confinement is similar to  with a constant Reynolds number
(5000), under various Richardson number from -1 to 1.
3-The velocity distribution and Nusselt number increased with increasing in Reynolds number
values and vice versa for the skin friction.
The flow is characterized by the Reynolds number
The exponents of the Reynolds number
in the first phase are slightly higher than for the previous section.
Therefore, relation for Sherwood number and air and falling film Reynolds number
is taken from the similar experiments conducted on the same experimental line.
In order to study the Reynolds number
effect on the deformation of the capsule, we simulate two additional Reynolds numbers
, Re = 0.
When the Reynolds number
is 1000, we obtain the streamline and three-dimensional graph by use of the MATLAB after 40000 steps of the calculation, as shown in Figures 6 and 7.
The mean nozzle outlet velocities were then used to calculate the Reynolds numbers
The viscosity property in flows with Reynolds number
is more important than inertia.
Variation of Nusselt number with flow regimes behind a circular cylinder for Reynolds numbers
from 70 to 30000.
This gives rise to a new question: why is the Reynolds number
the primary parameter determining transition to turbulence?
