Abstract
The problem of mixed convection over a semi-infinite vertical flat plate is studied by the method of series truncation for both cases when buoyancy adds and opposes the main flow. The present analysis is valid from leading edge to far downstream. The solutions show that the results are very accurate over an entire flow regime spanning from pure forced convection to moderately large free convection flows. In the buoyancy dominated limit the heat transfer is underestimated by 4 percent and skin friction is overestimated by 22 percent.
Zusammenfassung
Das Problem der gemischten Konvektion entlang einer vertikalen ebenen Platte wurde untersucht mit Hilfe der Methode der abgebrochenen Reihen, um Ergebnisse für kleine und mittlere Reynoldszahlen zu geben, verglichen mit den Grenzschicht-Resultaten in der Literatur, die fürRe→∞ gültig sind. Es wurde gefunden, dass die Methode gute Ergebnisse gibt für alle drei Regionen (erzwungene Konvektion dominierend im Nahgebiet, freie Konvektion dominierend im Ferngebiet, und das Zwischengebiet) in die das Strömungsfeld bei Grenzschichtrechnungen aufgeteilt worden ist; nicht nur für genügend grosseR x sondern auch für sehr kleine Werte vonR x .
