Left column demonstrates the temperature distribution and right column demonstrates the electric field distribution, both after 90 seconds of freezing with an applied voltage of 2000 V for 90 pulses. The first row illustrates the results due to 90 seconds of freezing and the second row illustrates the results due to 90 seconds of thawing. The trends are similar to those seen in the 1 V cases. However, in the freezing case, the electric field reaches a maximum of 100,000 V/m. In the thawing case the electric field reaches a maximum of 75000 V/m. The temperature rises more quickly at the leftmost plate in both the freezing and thawing cases due to Joule heating.
