Abstract: | The influence of thermocapillary stress on the shape of the gas-liquid phase boundary is investigated numerically. We consider
the case of a cold liquid meniscus at a heated solid wall in the absence of gravity. An “apparent contact angle” is defined
geometrically and the deviation of this apparent contact angle from the prescribed static contact angle due to thermocapillary
convection is studied. We observe an enlarged apparent contact angle compared to the isothermal case. Since a fixed static
contact angle is used in the computations, we emphasize that this effect does not depend on the specific model of a dynamic
contact angle. |
