WebHeat Flow on a Graph Simone, Mary Angelica, Chris July 18, 2014 1 Introduction Heat ow on a weighted graph with Nvertices is governed by the linear equation dx dt = Lx, where xis an N dimensional vector giving the temperatures at the vertices, and Lis the Laplacian matrix for the weighted graph. If x(t) is a solution to this equation, then lim ... WebSep 1, 2024 · As can be seen from the graph, ... During critical heat flux, the droplet evaporation behaviour was very active and the liquid disappeared very fast soon after it touched the hot surface. Surprisingly, when the surface temperature reached 151.3 °C, the evaporation lifetime suddenly rose up a bit to a higher value of 1.54 s. This sudden ...
