Transient Marangoni convection in a liquid droplet suddenly subjected to a parallel radiative heating is analyzed. The effects of the Marangoni number and the Prandtl number with respect to the developments of flow and temperature fields within the droplet are examined. The following results are obtained : (1) The flow pattern in the droplet changes little with the Marangoni number over a wide range (Ma=1〜10^4) ; (2) the dominant mechanism of heat transfer at early stages is conduction, but it is replaced by convection at later stages provided that the Marangoni number is over 100 ; (3) the developing time for the temperature field is almost independent of the Marangoni number ; and (4) the Prandtl number has little effect on the developing time for the temperature field.
