Under drag reducing flow, the main velocity profile shifts its shape to that of a laminar flow however, still remains certain level of turbulent intensities although quite weak than that of water flow under the same Reynolds number.
The maximum error between the numerical and the experimental data under the condition relative to the primary speed is about 15.35% at the position of 420mm from the lobe in the mixing section.
The maximum error between the numerical and the experimental data under the condition relative to the primary speed is about 21.65% at the position of 52mm from the lobe in the mixing section.
The film jet velocities varied from 15 to 143 m/sec. The mass flow rates M were 0.2-3.2. The mainstream temperatures changed from 40 to 148[℃]. The range of variation of the film temperature was 24 to 67[℃].
In the previous papers, we have discussed that when the heat flux density and main flux velocity were constant, the forced convection was influenced by the-natural convection, given "non-similar solution" and expanded if in Gr/Re5/2 series.
Second, the stream-wise exponential velocity decay is simulated, which simulates the particle tracers decelerating downstream of a shock wave and gives an example of a flow with main velocity differences aligned with the velocity direction.
We then discuss a general model, consisting of three main velocity regimes, in which we relate type II radio bursts and coronal shocks to optically-observed ejecta.
Data on coronal shocks and high-velocity ejecta from solar flares are then discussed in terms of a general model consisting of three main velocity regimes.
Good agreement was achieved for the main velocity component in both well-behaved flow (in the common carotid) and disturbed region (in the carotid sinus).
The primary speed bottleneck we encountered was file transfer from the camera to the laptop, which will hopefully improve in new camera systems.

The experimental adiabatic temperature ratios η were obtained for the turbulent film cooling over a flat plate. The mainstream velocities varied from 54 to 101 m/sec. The film jet velocities varied from 15 to 143 m/sec. The mass flow rates M were 0.2-3.2. The mainstream temperatures changed from 40 to 148[℃]. The range of variation of the film temperature was 24 to 67[℃]. The experimental correlations were presented in this paper.
This paper analysis the problem—how to determine the main stream velocity on the flanking rudder, the accelerating nozzle and the steering rudder in the prediction of maneuverability of a ship. This analysis, which considers approximately the influence exerted on the downstream by the upsteam in the nozzle-rudder configuration, is based on the theoretical results of the ducted propeller.
In this paper, an alternative method has been presented to solve the Orr-Sommerfeld equation in the linear theory of stability. To begin with, we define a Green function which is expressed in terms of matrix. Subsequently, the reciprocity of it has been shown. Finally, a linear integral equation that is equivalent to the original Orr-Sommerfeld equation is derived. The method is applied to the cases with two solid walls and any velocity distribution of the main flow at any Reynolds number.
