In this work, the effect of spatial distribution and values of the turbulent kinetic energy on the pressure-time history and then on the explosion parameters (deflagration index and maximum pressure) was quantified in both the standard vessels (20 L and 1 m³).

The turbulent kinetic energy maps were computed in both 20 L and 1 m³ vessels by means of CFD simulations with validated models. Starting from these maps, the turbulent flame propagation of cornstarch was calculated, by means of the software CHEMKIN. Then, the pressure-time history was evaluated and from this, the explosion parameters.

Calculations were performed for three cases: not uniform turbulence level as computed from CFD simulations, uniform turbulence level and equal to the maximum value, uniform profile and equal to the minimum value. It was found that the cornstarch in the 20 L vessel get variable classes (St-1, St-2, St-3) with respect to the 1 m³ (St-1). However, simulations performed on increasing the ignition delay time, shown that the same results can be attained only using 260 ms as ignition delay time in the 20 L vessel.

在这项工作中，在两个标准容器（20 L和1 m ³）中都定量了空间分布和湍动能值对压力时间历史的影响，然后对爆炸参数（爆燃指数和最大压力）的影响。 。

通过具有验证模型的CFD模拟，在20 L和1 m ^3的容器中计算了湍流动能图。从这些图开始，借助CHEMKIN软件计算了玉米淀粉的湍流火焰传播。然后，评估压力时间历史，并据此评估爆炸参数。

针对以下三种情况进行了计算：从CFD模拟计算得出的湍流水平不均匀，湍流水平不等于最大值且等于最大值，轮廓不均匀且等于最小值。已经发现，相对于1 m ³（St-1），20 L容器中的玉米淀粉具有可变等级（St-1，St-2，St-3 ）。但是，对增加点火延迟时间进行的模拟显示，只有将20升容器中的点火延迟时间设为260 ms才能获得相同的结果。
