NPCaviNus Find

NPCaviNus Find is a professional computing application designed for professionals in the field of engineering and physics and students of related majors, focusing on the precise calculation and in-depth analysis of the relationship between net positive suction head and cavitation, Nusselt number and oblique shock wave.

In terms of net positive suction head and cavitation calculation, the net positive suction head can be accurately calculated by inputting parameters such as liquid density, saturated vapor pressure, flow rate, system pressure, etc., effectively evaluating and predicting the risk of cavitation in the fluid system, providing key basis for the design and operation and maintenance of hydraulic machinery, ship propulsion systems, etc., and avoiding equipment damage and efficiency reduction caused by cavitation.

For Nusselt number calculation, according to different convective heat transfer scenarios, the thermal conductivity, characteristic length, convective heat transfer coefficient and other data of the fluid are input to quickly obtain the Nusselt number, which helps heat transfer research and heat exchanger design, optimizes heat transfer efficiency, and plays an important role in both industrial refrigeration and energy development.

In the calculation of the oblique shock wave relationship, only information such as the incoming flow Mach number and shock wave angle is needed to quickly determine the airflow parameters after the shock wave, such as changes in pressure, temperature, and speed. This is of great significance in aerospace, high-speed airflow research, etc., helping engineers and scientific researchers to deeply understand the characteristics and changing laws of high-speed airflow, and providing indispensable data support and theoretical verification for aircraft design, supersonic wind tunnel experiments, etc.
