A one - dimensional oceanic mixed layer model with the m - y level - 2 . 5 turbulence closure schemes is employed . the rate of energy loss by breaking waves is estimated by parameterization and incorporated into the model as a source of turbulence kinetic energy ( tke ) by modifying the existing surface boundary condition of tke equation . the velocity field and turbulence energy budget are calculated under different forcing conditions ( the results given below are for a wind speed of 20 m / s . ) 采用一维2 . 5阶湍封闭混合层模式，根据参数化方法对波浪破碎导致的能量耗散率进行了估计，通过改变湍动能方程的上边界条件引入波浪破碎对湍动能生成的影响，计算了不同风应力强迫下的混合层流场结构和湍能量收支(下述给出的结果是取风速为20m s得到的) 。
Planar laser induced fluorescence ( plif ) and multi - dimensional cfd software was used to study the fuel - air mixing process in traditional combustion chamber and bump combustion chamber , the experimental and simulated result agree well in room condition . the fuel - air mixing process in high pressure and temperature in traditional and bump combustion chamber were compared . the result show that fuel and air can mix more quickly in bump combustion chamber than in traditional combustion chamber , fuel - air mixture in bump combustion chamber is more homogenous than in traditional chamber 进一步对高温高压下传统燃烧室和bump燃烧室内燃油空气混合好坏进行了对比研究，提出了衡量燃油与空气混合好坏的三个指标，发现bump燃烧室内燃油能在更大的体积内与空气混合， bump燃烧室内燃油比传统燃烧室内燃油分布相对更均匀， bump燃烧室内燃油浓度耗散率为传统燃烧室内燃油耗散率2 . 8倍，能更快与空气混合。
