    Description / Table of Contents: Zusammenfassung Die Arbeit bezieht sich auf die numerische Simulation der physikalischen Phänomene in Wärmerohren, wobei insbesondere die Verdampfungsdynamik des Arbeitsmediums in einer Zweiphasen-Analyse untersucht wird. Mit Hilfe eines zeitabhängigen Differenzenverfahrens lassen sich die, die Wechselwirkung zwischen Dampfphase und Wasserpartikeln beschreibenden Gleichungen für den kompressiblen Fall lösen. Mittels eines dreistufigen Runge/Kutta-Verfahrens wird die Dampfdynamik analysiert, wobei durch Einführung eines Dämpfungsterms eine Stabilisierung des numerischen Verfahrens bewirkt wird. Ein praktisches Berechnungsbeispiel schließt die Untersuchung ab.
    Notes: Abstract This paper presents numerical simulation of the physical phenomena in heat pipe. The vapour dynamics of working fluid is considered in the numerical analysis of the heat pipe. A two-phase analysis is carried out for the heat pipe. The compressible flow equations for vapour-phase interaction with water particle phase are solved by a finite volume technique. A three stage Runge-Kutta time-stepping method is employed to solve vapour dynamics. Damping term is added to stablize the numerical scheme. An example is worked out to study the two phase flow in the heat pipe.

    Notes: A numerically fast algorithm has been developed to solve the viscous two-phase flow in an axisymmetric rocket nozzle. A Eulerian-Eulerian approach is employed in the computation to couple the gas-particle flow. Turbulence closure is achieved using a Baldwin-Lomax model. The numerical procedure employs a multistage time-stepping Runge-Kutta scheme in conjunction with a finite volume method and is made computationally fast for the axisymmetric nozzle. The present numerical scheme is applied to compute the flow field inside JPL and AGARD nozzles. © 1998 John Wiley & Sons, Ltd.
