Pipe flow problems are important in transportation of wastewater, oil lines and supply of water. In this study, a non-Newtonian fluid model is discussed and a CFD solution is presented for flow geometry. The effects on velocity, pressure, dynamic viscosity and cell Reynolds number are discussed for different parameters of flow inside the pipe. Power Law function is considered in the analyses. The velocity profile increased and get more parabolic distribution when flow behaviour index, n was increased. That supports lower pressure profile in the pipe flow. The lowest n value causes to increase the sensitivity for viscous effects. The increased flow consistency index, K causes to increase dynamic viscosity but decreases the Re number. Results are given in different graphs and contours.

Die vorliegende Arbeit bringt eine theoretische Untersuchung der laminaren Grenzschichtströmung einer dem Potenzgesetz gehorchenden nichtnewtonschen Flüssigkeit hinter einer beliebigen zweidimensionalen Fläche. Es wird eine Form der Grenzschichtgleichung hergeleitet, die in der Hinsicht universell ist, daß weder die Gleichung noch die Randbedingungen von den besonderen Bedingungen des Problems abhängen. Dies wird dadurch erreicht, daß in die Zahl der unabhängigen Variablen eine Schar von Parametern einbezogen wird, die den Einfluß der für ein spezielles Problem charakteristischen Bedingungen ausdrücken. Die universelle Gleichung wird durch eine Parameterapproximation numerisch gelöst. Mit Hilfe dieser Lösung werden mehrere spezielle Probleme im Detail diskutiert.
