In this paper. the dynamic behavior of gas bubbles and flow in a liquid-gas-solid oscillatory baffled reactor (OBR) was analyzed. A method based on baffle and oscillating flow induced vorticity was employed to analyze the dynamic gas bubble behavior and elucidate key parameters that govern the flow phenomena and reactor performances. Through visualization experiment for gas flow. https://parisnaturalfoodes.shop/product-category/b-100/
