Liutex es una nueva cantidad física introducida por el profesor Chaoqun Liu de la Universidad de Texas en Arlington. Es un vector y podría dar una definición matemática única y precisa de rotación de fluidos o vórtice. Los artículos de este volumen incluyen algunas teorías de Liutex y muchas aplicaciones en hidrodinámica, aerodinámica y dinámica térmica, incluida la maquinaria de turbinas. Como los vórtices existen en todas partes del universo, una definición matemática de vórtice o Liutex desempeñará un papel fundamental en la investigación científica. Casi no hay lugar sin vórtices en dinámica de fluidos. Como proyección, la teoría de Liutex jugará un papel importante en las investigaciones de la dinámica de los vórtices en hidrodinámica, aerodinámica, termodinámica, oceanografía, meteorología, metalurgia, ingeniería civil, astronomía, biología, etc. y en las investigaciones de la generación, sustento. , modelado y control de turbulencias.
