Numerical Modeling of the Photothermal Processing for Bubble Forming around Nanowire in a Liquid

Abstract EN

An accurate computation of the temperature is an important factor in determining the shape of a bubble around a nanowire immersed in a liquid.

The study of the physical phenomenon consists in solving a photothermic coupled problem between light and nanowire.

The numerical multiphysic model is used to study the variations of the temperature and the shape of the created bubble by illumination of the nanowire.

The optimization process, including an adaptive remeshing scheme, is used to solve the problem through a finite element method.

The study of the shape evolution of the bubble is made taking into account the physical and geometrical parameters of the nanowire.

The relation between the sizes and shapes of the bubble and nanowire is deduced.
