Velocity and temperature distributions of turbulent plane jet interaction with the nonlinear oppositive progressive wave

The paper extends the analytical results obtained by Hwung et al.
(1981) and further considers the non-linearity of waves to investigate
variation horizontal velocity, temperature distribution induced by
interaction of 2-D plane jet and waves. On the steady state, the nonlinear
wave is considered as external force in motion equations, the property of
momentum conservation of jet flow, and radiation stress are applied to
analyze the interaction of waves- jet flow in arbitrary profile. The scale
function 1
£` £\1(x) , 2
2£` £\ (x) between the variation function f (x,y) and
velocity distribution can also be obtained. The non-dimensional
theoretical solution is also useful to estimate the relative characteristics in
the physical field. The momentum equation and velocity distribution of
interaction without property of temperature diffusion are employed to
find the temperature distribution for arbitrary sections.
Based on the experiments and theory solution obtained by Hwung et
al. (1981) it is found that time-averaged horizontal velocity and
temperature are Gaussian distribution, the coefficient of horizontal
velocity 1 c , and temperature distribution 2 c are 0.105, 0.148, respectively.
In the present, two coefficients considered as non-linearity of waves
1 c = 0.124 and 2 c = 0.152 are determined. In other words, it is shown that
exact solution and boundary effect included non-linearity of waves is
related to velocity of jet flow, wave periods, relative depth and steepness
of waves respectively.
Comparing with experiments indicated that the analytical solution of
the present for MSE is well confirm the experimental results and better
than linear results obtained by Hwung et al. (1981) The influence due to
interaction of 2-D turbulent jet flow and Stokes waves can be obtained by
using dimension analysis. Moreover, the related properties inside the flow
also can be estimated.
