Abstract

As an important secondary energy, steam is widely used in engineering for its role of heat transfer and mechanical transmission. But steam is a complex medium, its state easily changes as the working condition changes, thus causes measurement error. Based on the present situation, a theoretical analysis has been made on vortex flow meter, which proved that the error was related to steam dryness. Numerical simulations were made to verity that measuring accuracy was related to the droplet diameter condensed out from the steam.
