Any mixing of fluid phases is\n\tavoided by using the flow solver in the bulk regions only, and a\n\tghost-fluid approach close to the interface. The coupling states\n\tfor the numerical solution in the bulk regions are determined by\n\tthe solution of local multi-phase Riemann problems across the interface.\n\tThe Riemann solution accounts for the relevant physics by enforcing\n\tappropriate jump conditions at the phase boundary. A wide variety\n\tof interface effects can be handled in a thermodynamically consistent\n\tway. This includes surface tension or mass/energy transfer by phase\n\ttransition. Moreover, the local normal speed of the interface, which\n\tis needed to calculate the time evolution of the interface, is given\n\tby the Riemann solution. The interface tracking itself is based on\n\ta level-set method. The focus in this paper is the description of\n\tthe multi-phase Riemann solver and its usage within the sharp interface\n\tapproach. One-dimensional problems are selected to validate the approach.\n\tFinally, the three-dimensional simulation of a wobbling droplet and\n\ta shock droplet interaction in two dimensions are shown.

Due to additionally induced turbulence in the flow field,\n the heat transfer is increased. This study focuses on different pin fin\n arrays with thermally inactive pin fins. The configurations Include\n short and long elements. Transient experiments are conducted to\n determine the heat transfer characteristics on the endwall. Therefore,\n the transient liquid crystal technique is applied to obtain locally\n resolved heat transfer data. Three configurations with a relative\n spacing of 2.5 <= S/D <= 5 and aspect ratio of 2 <= H/D <= 4 are\n investigated. Hereby, the Reynolds number of the air flow, based on the\n pin fin diameter, varies from 3 . 10(3) to 3 . 10(4). First, an overview\n of the experimental setup and the transient measurement technique is\n given. Then, heat transfer results on the endwall are presented in terms\n of Nusselt number. Finally, the pressure drop is evaluated by the\n friction factor and the thermal performance of the investigated\n configurations is discussed. (C) 2016 Elsevier Ltd.
