  1. How Do Cavitation Heat Generators Work? Cavitation heat generators (CHGs) are an innovative heating technology that transforms mechanical energy into heat by harnessing controlled cavitation — the formation and collapse of vapor bubbles in liquid. Unlike conventional systems, CHGs offer high energy efficiency, clean operation, and low maintenance, making them ideal for modern heating needs. What is Cavitation? Cavitation happens when pressure in a liquid drops below its vapor pressure, forming bubbles that violently collapse, releasing heat, shock waves, and mechanical energy. CHGs control this process to generate heat effectively and safely. System Design & Operation Most CHGs use a rotor-stator hydrodynamic system: •Rotor spins liquid inside a cavitation chamber •Rapid pressure changes create and collapse vapor bubbles •A circulation system moves fluid through the system •Heat is released and transferred via convective flow to the application (water heating, space heating, etc.) Advanced designs include multi-zone reactors, adjustable geometry, and hybrid heat sources for enhanced performance.

  2. Physics of Heat Generation Energy is released in multiple forms during cavitation: •Kinetic energy from bubble collapse •Thermal energy through compression •Acoustic energy that dissipates into heat Performance depends on factors like rotational speed, fluid temperature, pressure differential, and working fluid properties.
