Abstract

In this study, an analysis of laminar forced convection in a plane duct for a power-law fluid with constant thermophysical properties is performed by taking the viscous dissipation into account. This part of the study, Part 1, examines both hydrodynamically and thermally fully developed flow case. Two different thermal boundary conditions are considered: the constant heat flux (H1 boundary condition) and the constant wall temperature (T boundary condition). The combined and interactive influences of the power-law index and the Brinkman number on temperature distribution and the Nusselt numbers are analytically determined both for the wall heating and cooling cases at T and H1 boundary conditions. Singularities are observed in Nu-Br-n behaviors and these are discussed in terms of the energy balance.

Özet

Bu çalışmada, sabit termofiziksel özelliklere sahip power-law akışkanın düzlemsel kanal içerisindeki laminer zorlanmış taşınımı, viskoz yayılım etkileri dahil edilerek, analiz edilmiştir. Çalışmanın bu bölümünde, birinci hidrodinamik ve termal açıdan tam gelişmiş akış incelenmektedir. Sabit ısı akısı (H1 sınır koşulu) ve sabit yüzey sıcaklığı(T sınır koşulu) olmak üzere iki farklı termal sınır koşulu ele alınmıştır. Power-law indeksi ve Brinkman sayısının sıcaklık dağılımı ve Nusselt sayısı üzerindeki etkisi, T ve H1 sınır koşullarında, sıcak ve soğuk cidar durumları için analitik olarak belirlenmiştir. Nu-Br-n davranışlarında süreksizlikler gözlenmiş ve bu süreksizlikler enerji dengesi açısından tartışılmıştır.
