Hydrodynamic cavitation occurs when vapor bubbles form and subsequently collapse due to localized pressure drops in a flowing fluid. This phenomenon holds significant potential for applications such as microalgae cell disruption, as the collapse of bubbles releases high-energy shockwaves capable of rupturing robust cell walls. The primary objective of this thesis was to investigate whether hydrodynamic cavitation could be effectively exploited for lysing Galdieria sulphuraria microalgae. The research focused on the hydrodynamic characterization necessary to optimize microalgae cell disruption. Experiments were conducted using a custom-designed stainless-steel hydraulic circuit, incorporating interchangeable orifice plates with diameters of 2 mm, 3 mm, 4.5 mm, and 6 mm.
