Computational one-factor investigation on the effect of sonication parameters in biomass pretreatment

Abstract

The application of ultrasonic irradiation has been proven as a clean and efficient approach for biomass pretreatment process. However, the effects of sonication parameters on the performance of biomass pretreatment are not well discussed due to its physical complexity. The current work aims to model Rayleigh-Plesset equation (RPE) to investigate how the fluid property of biomass-water (surface tension and dynamic viscosity) and sonication parameters (sonication frequency and power) influence the growth and bounce of microbubbles. The collapsing temperature, collapsing pressure, and shock pressure are computed. Moving Least Squares and Multivariable Power Least Squares Method are applied for multivariate investigation. The results revealed that fluid properties are more significant than sonication parameters.
