Summary
The second-order heat flux in thermally driven oscillations of gas columns is calculated and given in a form suitable for numerical evaluation. Order-of-magnitude estimates are made in the case of steep temperature gradients.
Zusammenfassung
Der Wärmestrom zweiter Ordnung, der in thermisch getriebenen akustischen Schwingungen einer Gassäule entsteht, wurde berechnet und ist in einer für numerische Rechnungen geeigneten Form angegeben worden. Die Grössenordnung des Effektes wurde für steile Temperaturgradienten abgeschätzt.
