چکیده
1. Abstract This paper presents a topology optimization method using the lattice Boltzmann method for the design of a flow channel considering two-phase fluid flows. This approach enables the design of fluidic devices such as two-phase microchannels that achieve a desired flow with maximal performances such as mixing and reaction, and extraction efficiencies. The optimization problems are formulated using the continuous Boltzmann equation, and the design sensitivities are derived based on the adjoint lattice Boltzmann method. In the adjoint lattice Boltzmann method, based on a novel discretization strategy similar to that of the lattice Boltzmann method, the adjoint equations can be implemented as simple time evolution equations. Based on the above formulations, we construct a topology optimization method incorporating level set boundary expressions for the design of a two-phase microchannel that aims to maximize extraction efficiency while minimizing the pressure drop. A numerical example is provided to confirm the utility of the proposed method. 2.

World Congress on Structural and Multidisciplinary Optimization
1. Abstract It has become apparent that as modern day large-scale systems become increasingly complex the traditional Multidisciplinary Design Optimization (MDO) Systems Engineering design philosophy is becoming problematic. The communication of preferences through requirements has resulted in arbitrarily chosen constraints and objective functions attempting to reflect the stakeholder’s desires...
