MLKewisNum is a professional application that focuses on the calculation of key parameters of fluid and gas dynamics. It provides a very convenient and accurate calculation tool for aerospace engineers, thermodynamic researchers, fluid mechanics scholars and students of related majors.

In the field of microfluid or rarefied gas research, the Knudsen number calculation function is of key significance. Users only need to enter parameters such as the mean free path of molecules and characteristic length, and the APP can quickly obtain results based on the definition formula of the Knudsen number. The Knudsen number is used to determine whether the fluid flow state is in the continuous medium region, transition region or molecular flow region, which is indispensable for microchannel fluid flow analysis in microelectromechanical systems (MEMS), gas transport research in nanotechnology, and aircraft design in high-altitude rarefied gas environments. For example, when designing micro-nanoscale sensors or microfluidic chips, accurate Knudsen number calculations can help engineers understand and predict fluid behavior, optimize device structure and performance, and ensure their normal operation under specific working conditions.

Lewis number calculations play an important role in the study of heat and mass transfer coupling processes. Users provide data such as the thermal diffusivity and mass diffusivity of the substance, and the APP can accurately calculate the Lewis number. It reflects the relative size of heat diffusion and mass diffusion rate, and is widely used in combustion process analysis, multiphase flow systems in chemical reaction engineering, and pollutant diffusion research in atmospheric science. Through the calculation of Lewis number, researchers can deeply explore the mechanism of heat and mass transfer interaction, and provide a strong basis for optimizing combustion efficiency, controlling chemical reaction processes, and predicting environmental pollution diffusion.

Mach number calculation is one of the core parameters in high-speed gas dynamics research and aircraft design. Input information such as gas flow rate and local sound speed, and APP quickly obtains the value based on the definition of Mach number. Mach number is used to measure the supersonic or subsonic degree of gas flow, and plays a key role in the aerodynamic shape design, engine inlet design, and flight performance prediction of aircraft, rockets and other aircraft in the aerospace field. For example, in the design of supersonic aircraft, accurate Mach number calculation can help engineers evaluate the impact of air compressibility on the aerodynamic characteristics of the aircraft, optimize the flight trajectory and control strategy, and ensure the stability and safety of the aircraft during high-speed flight.

The MLKewisNum APP is not only accurate in calculations, but also equipped with detailed theoretical explanations, example demonstrations, unit conversion and other auxiliary functions. It is your powerful partner in exploring and researching the field of fluid and gas dynamics, helping you to deeply understand and solve complex scientific and engineering problems.
