dc.description	Videos of the numerical simulation of vertical drop coalescence on smooth, superheated walls. The videos show the following cases: successive drop impingement with a time interval of 2.4 ms, 5 ms, 7.6 ms, 12 ms, 22 ms, 32 ms, 38 ms, and 50 ms as well as the single drop impingement with a double volume and drop train impingment with a time interval of 100 ms as well as drop trains with 1, 4, 16, and 2000 drops. Impact parameters such as initial drop diameter, impact velocity, and wall superheat are 1.14 mm, 0.54 m/s, and 9.8 K, respectively. Dimensionless numbers such as Reynolds, Weber, Bond, and Jakob numbers are 2230, 62.4, 0.6, and 0.13, respectively. The impact parameters and dimensionless numbers of the drop train impingement can vary because the total kinetic energy and flow rate are kept constant. 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.	de_DE
