Description

Videos of the numerical simulation of drop array impingement onto smooth, superheated walls. The videos show the following cases: drop array impingement with a spacing of 1.18, 2.15, and 3.33. Impact parameters such as initial drop diameter, impact velocity, and wall superheat are 0.93 mm, 0.53 m/s, and 7.3 K, respectively. Dimensionless numbers such as Reynolds, Weber, Bond, and Jakob numbers are 1775, 48.8, 0.4, and 0.09, respectively. The working fluid is perfluorohexane (FC-72) in a pure vapor atmosphere of the same fluid at ambient pressure. The simulations are carried out in OpenFOAM.
