High-order hydrodynamics and boundary conditions. Application to the thermal force

Гидродинамика высшего порядка и граничные условия. Применение к термальной силе

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

For higher-order constitutive laws boundary conditions are derived by a thermodynamic method due to Waldmann. The application to the thermal force yields an expression which can account for the experimental data over a wide range of Knudsen numbers and all ratios of the heat conductivities of the aerosol particle and the gas.

Riassunto

Con un metodo termodinamico dovuto a Waldmann si ottengono condizioni ai limiti per le leggi costitutive di ordine superiore. Applicandole alla forza termica si ha un’espressione che soddisfa i dati sperimentali per un esteso intervallo di numeri di Kundsen e per tutti i rapporti di conducibilità termica delle particelle in aerosol e dei gas.

Резюме

Используя термодинамический метод, разработанный Вальдманом, выводятся граничные условия для конститутивных законов высшего порядка. Применение к термальной силе приводит к выражению, которое может объяснить экспериментальные данные в широкой области чисел Кнудсена и всех отношений удельных теплопроводностей аэрозольной частицы и газа.
