Observation of the boundary layer is important to examine phenomena of boiling when a non uniform electric field is applied. Accordingly, temperature changes near the boundary layer were observed by the Schlieren method using a nickel-chrome fine wire as the heater and a rod as the electrode to which alternate current up to 1000 volts was applied. The result shows that the temperature boundary layer is disturbed by the electric field and the stronger the turbulence, the higher the applied electric field. The bubbles generated on the heater are released through the boundary layer and expand outside of the boundary layer. The turbulence in the boundary layer was observed as stripes arranged relatively regularly. The interval of the stripes in the temperature boundary layer decreased as the applied electric field increased.
