Acoustic Simulation for Process Analysis of Sonochemical Reactor

H. Matsumoto
Tokyo Institute of Technology, Tokyo, Japan

We exhibit an application method of the acoustics module for numerical simulation of sound pressure distribution inside/outside a reactor under the indirect irradiation of ultrasounds. Applicability of the sound pressure simulation to design of sonochemical reactor is shown by comparison with experimental results for the process analysis of emulsion polymerization using ultrasounds.

Using COMSOL with the Adjoint Method for Inverse Problems

A. Emery
University of Washington, Seattle, WA, USA

The standard way of estimating parameters in solving inverse problems is based upon least squares fitting which minimizes the sum of the residuals. Another way of minimizing is based upon the adjoint approach in which the sum of the residuals is augmented by the constraint that the solution satisfies the appropriate algebraic or differential equations. This method involves solving the adjoint ...
