Summary

A first-order boundary-layer analysis, including variable properties effects, is given for laminar natural convection on a horizontal circular disc. It is shown that the result for the Nusselt number is very close to that for a square plate.

Zusammenfassung

Eine Grenzschichtsanalyse erster Ordnung, einschliesslich der Wirkung variabler Stoff-Eigenschaften, wird für laminare natürliche Konvektion auf einer horizontalen kreisrunden Platte angegeben. Es wird gezeigt, dass das Ergebnis hinsichtlich der Nusselt-Zahl demjenigen für eine viereckige Platte sehr ähnlich ist.
