项目摘要
9314465 Wang The main objective of this study is to understand the growth process of ice particles in clouds and precipitation. The study will investigate the growth of large particles where the particles perform oscillating motions in air. The PIs will study both the diffusional growth and riming of ice particles in two contexts, i.e., from both the individual particle and cloud dynamical points of view. To achieve the first goal, they will numerically solve the unsteady Navier-Stokes equations for flow past ice particles of various shapes and then use the flow fields so obtained to determine the diffusional growth and riming by solving the convective diffusion equations of vapor and the equation of motion of supercooled droplets. To achieve the second goal, they will parameterize the results obtained and incorporate them in a cloud dynamical model. Finally, they will participate in the WISP94 experiment to collect real ice samples and use their models to interpret the observation. ***
小行星9314465 本研究的主要目的是了解云和降水中冰粒的生长过程。 该研究将调查大颗粒在空气中进行振荡运动的生长情况。 PI将在两种情况下研究冰粒的扩散生长和边缘化,即,从单个粒子和云动力学的角度来看。 为了实现第一个目标,他们将数值求解流经各种形状的冰粒的非定常纳维尔-斯托克斯方程,然后通过求解蒸汽的对流扩散方程和过冷液滴的运动方程,使用由此获得的流场来确定扩散增长和结霜。 为了实现第二个目标,他们将对获得的结果进行参数化,并将其纳入云动力学模型。 最后,他们将参加WISP 94实验,收集真实的冰样本,并使用他们的模型来解释观测结果。 ***
