Firstly, the two parts are solved separately, and the results are then coupled together. Because the thickness of the combustion reaction zone at high Re and Da numbers is less than the turbulent diffusion scale in diesel engines, the flame is extremely thin, its micro-structure keeps the laminar structure, so the turbulent flame can be regard as the ensemble of locally one dimensional, thin laminar flamelet embedded within the turbulent flow field.

由于柴油机中在高雷诺数和高Damkoeler数的情况下，燃烧反应区厚度小于湍流耗散尺度，火焰极薄，其微元保持层流结构，因此，湍流火焰可视为嵌入湍流流场内局部具有一维结构的薄的层流小火焰的系综，这便构成了层流小火焰模型主导思想，同时也使层流小火焰模型模拟柴油机湍流燃烧过程成为可能。

The effect of Reynolds number on rudder hydrodynamic performance is also analyzed. Up to the stall angle the computed lift and drag agree well with measurements and other author's calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under-predicted.

The second separation flows are successfully identified in both laminar and turbulent flow simulations.

"We decided to quantify the calcium findings in the aorta and stratify calcium by total score, as well as scores in suprarenal, laminar, and bifurcation segments," Dr. Davila said. In general, the highest calcium scores were found in the laminar area, but "these scores did not correlate with a statistically significant increased risk." By contrast, a total calcium score or bifurcation score above the 75th percentile "correlated with a 10-fold increase in risk of cardiac event," he said.

Davila医师表示，我们决定主动脉钙含量的发现、利用总分来分类钙含量，以及肾脏上方、薄层、分支区段的指数；一般而言，指数最高的位置在於层状区域，但是这些指数与心血管风险的增加之间并没有显著的关连；相反的，总钙含量指数或是分支区段指数高於四分位数前75%者，与增加10倍心血管疾病的风险有关。

The highest heat transfer coefficient for air flowing in the nine 3-D IFT with staggered arrangement fins is No9 tube. In the turbulent region, the heat transfer coefficient of No9 tube is a factor of 10.36 compared with smooth tube, and its thermodynamic performance coefficient is as high as 6.49; The average Nusselt number in the most superior 3-D IFT with staggered arrangement can be increased by about 1.04 times in the laminar flow, and 6.38 times in the transitional flow as compared with that in the smooth tube. The friction factor between fluid and tube wall can be 0.96 times in laminar flow, and 12.68 times in transitional flow as compared with that inside the smooth tube.

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?
