Wärmeübergang bei turbulenter freier Konvektion an senkrechten Zylindern

Abstract

Fur den Warmeubergang an senkrechten Zylindern bei turbulenter freier Konvektion werden die Impulsgleichung und die Energiegleichung der Grenzschicht gelost. Dabei werden fur die Geschwindigkeits- und Temperaturverteilung Ansatze von Eckert und Jackson gewahlt, die das 1/7-Potenzgesetz bei turbulenter Stromung berucksichtigen. Ihre Ansatze werden mit dem ParameterH/D in der gleichen Weise erweitert, die sich beim laminaren Warmeubergang bewahrt hat, damit sie auch die Abhangigkeit von der radialen Koordinate beschreiben konnen. Die Parameter dieser Ansatze werden in Beziehung zu den Parametern bei Warmeubergang an der senkrechten Wand gleicher Hohe bei gleichen Randbedingungen gesetzt. Mit der Losung wird die mittlere Nuseitzahl als Funktion der Grashofzahl, der Prandtlzahl und des Parameters Hohe/Durchmesser berechnet.
