Development of computational biomechanics of gastric mixing

我们开发了一个计算流体动力学模型的胃混合。数值模型的边界条件为胃窦收缩波的动壁条件和胃气体的自由表面条件。我们研究了生理条件如食物团的粘度和体积以及胃窦收缩波模式对胃中混合效率和流体应力的影响。

We developed a computational fluid dynamics model of gastric mixing. Moving wall condition of antral contraction wave and free-surface condition of gastric gas were given as boundary conditions of the numerical model. We investigated the effects of physiological conditions such as the viscosity and volume of food bolus and the antral contraction wave pattern on the mixing efficiency and fluid stress in the stomach.
