The flows examined have Reynolds numbers within the range 0.05∼50. SPH results agree well with analytical solutions for those situations amenable to an analytical treatment, with the largest deviation being less than 2.0 %. The accuracy of a SPH formulation for heat convection, with particular emphasis in the viscous heat dissipation, is also tested via a steady convective heat transfer case for a combined Poiseuille and Couette flow. Abstractde SPH-Simulation ebener Scherströmungen bei niedrigen Reynoldszahlen und Wärmekonvektion Im Rahmen dieser Arbeit wird eine Reihe programmierbarer SPH-Formulierungen zusammnegestellt, die zur Simulation transienter ebener Scherströmungen, d. h. Poisson- und Couette-Strömung mit verschiedenen Arten von Volumenkräften, benutzt werden. Die untersuchten Strömungen haben Reynolds-Zahlen im Bereich 0.05∼50. Die SPH-Ergebnisse zeigen eine gute Übereinstimmung mit analytischen Ergebnissen, wobei die größte Abweichung kleiner als 2,0 % ist. Die Genauigkeit einer SPH-Formulierung für konvektive Wärmeübertragung unter besonderer Berücksichtigung der viskosen Wärmedissipation wird bei stationärer konvektiver Wärmeübertragung mittels einer kombinierten Poisson/Couette-Strömung getestet.
