Narrow Results

Recent results on multi-strange and heavy flavor production at RHIC are discussed and compared with model predictions. The idea of heavy flavor collectivity and light flavor thermalization is presented in the light of recent heavy flavor measurement at RHIC.

A new analytical approach is presented for analysis of two-particle azimuthal correlations in heavy ion collisions at relativistic energies. This approach suggests that elliptic flow measured by experiment has a compound structure, namely, that it may come from superposition of several components. General expressions have been derived for the two-particle correlation function isolating the contribution due to anisotropic flow. The model of compound flow takes into account the number of jets per event, average multiplicity per jet, dependence of jet yield on the orientation with respect to the reaction plane, and independent "soft" particle production. These analytic calculations provide the framework for a consistent description of the elliptic flow measured via the single-particle distribution with respect to the reaction plane, jet yield per event, and the amplitude of flow-like modulation in the two-particle distribution in the relative azimuthal angle.

Nowadays, several types of infusion pumps are commonly used for drug delivery, such as syringe pumps and peristaltic pumps. These instruments present different measuring features and capacities according to their use and therapeutic application. In order to ensure the metrological traceability of these flow and volume measuring instruments it is necessary to use suitable calibration methods and standards. Two different calibration methods can be used to determine the flow error of infusion pumps. One is the gravimetric method, considered as a primary method and commonly used by National Metrology Institutes. The other is a comparison method where an Infusion Device Analyser (IDA) is used as flow generator, and is typically used in hospital maintenance offices. The uncertainty calculation for the gravimetric method is very well described in the literature but for the comparison method no information regarding the uncertainty evaluation and components is available. This paper will describe in detail the measurement model along with the standard uncertainties components, the sensitivity coefficients values, the combined standard uncertainty and the expanded uncertainty of the comparison calibration method using an IDA, considering GUM methodology. This work has been developed in the framework of the EURAMET EMRP MeDD (HLT07) and EMPIR InfusionUptake (15SIP03) projects.

For orifice plate discharge tunnel, flow pulsation is closely related with cavitation and discharge tunnel's safety. In the present paper, the characteristics of orifice plate flow pulsation and its effects on cavitation are researched. The research results show that orifice plate flow turbulence belongs to low frequency and large pulsation. Orifice plate flow pulsation pressure is related with orifice plate's contraction ratio and it increases orifice plate's cavitation damage risk. When taking into account orifice plate cavitation, flow pulsation pressure must be paid attention to.

Heat pipes are devices of very high heat transfer capability and have been widely used in many thermal management applications. An experimental investigation and CFD simulation of thermal characteristics of heat pipe was presented in this paper. It can be found that UDF in FLUENT can simulate the evaporation and condensation in heat pipe. Phase change happened in evaporation section of heat pipe is boiling. In steady state, the fluctuation of axial velocity is very small in the most area (without evaporation section) in heat pipe. In general, the magnitudes of velocity vary from 0 to maximum from the end of both evaporation section and condenser, and the maximum value was maintained in the adiabatic section.
