1.(3)The distribution law of tangential velocity was: the center of eddy belong to enforce eddy move and the distribution law of velocity and pressure obey the law of forced eddy move which should be followed as : u_θ= cr~n, ( n >0> r >1) .
3.the period of July and August is its strongest stage during which the eddy extends to 112.50°E and its maximum tangential velocity reaches 30 cm/s,and the eddy center moves northeastward to(110.50°E,(13.25)°N);
4.(2) a cyclonic eddy is found on the mean currents observed in summer season. Vertical velocity is estimated to be about 10~4-10~3 m/s in the cyclonic eddy region.
5.Thrid, layering horizontal eddy diffusivity patterns within TL are used, Fourth, new dry deposition velocity pattern including the effect of plant canopy layer vertical structure is adopted.
6.Using the large eddy simulation (LES) and finite difference scheme, three-dimension simulation of the velocity field around a square cylinder at a Reynolds number of 22,000 is conducted.
8.The cool-core eddy displays prominent seasonal variation: The period of May and June is its developing stage during which it reaches 110.75°E and its maximum tangential velocity is 8cm/s;
9.The empirical equations for calculating eddy viscosity in the cyclone was given on the basis of the measurement results. The expression of the radial velocity was suitably assumed and the flow field in the separation space of the separator was regarded as an axi-symmetric flow field.
10.Combined with such method, the large eddy simulation (LES) technology is employed for numerical simulation of the center shift of fire whirl, and the important parameters such as average angular velocity, peak of temperature, location of the high temperature center are obtained. [
