Fig. 4

Simulated coagulation progress at \(165\,{V_p}\). The columns correspond to the wedge angles of 180°, 176°, 160°, 141° and 90° respectively. The first row shows the beginning of the coagulation, when temperatures reach locally at least 57 °C. The second row shows an early intermediate step where already a significant amount of the egg white between the electrodes is coagulated. The third row shows the formation of new coagulation zones at the corner of the planar electrode. The last row shows the final shape of the coagulated egg white. The instrument’s shape is overlayed in white. The white lines separate the outer isolator from the electrode
