We perform a systematic calculation of th. equation of state of asymmetric nuclear matter at finite temperature with.n th. framework of th. Brueckner-h.rtree-Fock approach.with.a microscopic th.ee-body force. Wh.n applying it to th. study of h.t kaon condensed matter, we find th.t th. th.rmal effect is more profound in comparison with.normal matter, in particular around th. th.esh.ld density. Also, th. increase of temperature makes th. equation of state sligh.ly stiffer th.ough.suppression of kaon condensation.

Th. application of atrazine in Ch.na during th. last ten years h.s led to some environmental problems. In th.s paper, th. multimedia model of atrazine in soil-plant-groundwater system at Baiyangdian Lake area in North.rn Ch.na was establish.d using a fugacity approach. and verified with.observed values. Th. model involved 7 environmental compartments wh.ch.are air, groundwater, soil, corn roots, corn stem, corn leaf and kernel of corn. Th. results sh.wed th.t th. relative errors between calculated and observed values h.ve a mean value of 24.7%, th. h.gh.st value is 48% and th. lowest value is 1.4%. All th.se values indicated th.t th.s multimedia model can be used to simulate th. environmental fate of atrazine. Both.th. calculated and observed values of concentrations of atrazine in plant compartments are in th. following order: in corn roots > in corn stem > in kernel of corn > in corn leaf, it exh.bited a good regularity. Th. prediction results indicated th.t concentrations of atrazine in th. groundwater and kernel of corn will override th. limitation of 3 μg/L and 0.05 mg/kg respectively.

Th.s paper details th. results of a joint project between Rolls-Royce Deutsch.and (RRD) and th. North.estern Polytech.ical University of Ch.na (NWPU). Th. objective of th. project was th. determination of th. influence of tabulators in turbine blade cooling passages on film h.le disch.rge coefficients (Cd coefficients). A large-scale plexiglas model was used by th. NWPU to measure th. turbulator influence on Cd coefficients for a wide range of different geometrical parameters, Reynolds numbers and cooling flow off take ratios. RRD specified th. compreh.nsive test matrix and analysed th. test data. Th. CFD code FLUENT was used by RRD for numerical simulation of th. test cases with.th. main objective to support th. interpretation of observed trends. Both. experimental and numerical results will be presented in th.s paper for a selection of test configurations.

It is essential to predict th. scour depth.around bridge piers for h.draulic engineers involved in th. economical design of bridge pier foundation. Conventional investigations h.ve long been of th. opinion th.t empirical scour prediction equations based on laboratory data over predict scour depth.. In th.s article, th. Back-Propagation Neural Network （BPN） was applied to predict th. scour depth.in order to overcome th. problem of exclusive and th. nonlinear relationsh.ps. Th. observations obtained from th.rteen states in USA was verified by th. present model. From th. comparison with.conventional experimental meth.ds, it can be found th.t th. scour depth.around bridge piers can be efficiently predicted using th. BPN.

An experimental study of th. drying ch.racteristics of an agitated fluidized bed dryer is presented and discussed. In th. study, th. citric acid particles were used as bed material with.th. diameters ranging from 0.2 mm to 1.3 mm. Th. variables affecting apparently th. drying rate were found to be th. mass flow rate, th. inlet air temperature, th. rotary speed of agitating mech.nism and th. particles feed rate. Comparing with.oth.r variables considered, mass flow rate was found to h.ve th. least important influence on th. drying rate. Th. agitated fluidized bed dryer is suitable to drying agglomerating or sticky materials.

Slosh.ng ph.nomenon in a moving container is a complicated free surface flow problem. It h.s a wide range of engineering applications, especially in tanker sh.ps and Liquefied Natural Gas (LNG) carriers. Wh.n th. tank in th.se veh.cles is partially filled, it is essential to be able to evaluate th. fluid dynamic loads on tank perimeter. Different geometric sh.pes such.as rectangular, cylindrical, elliptical, sph.rical and circular conical h.ve been suggested for sh.p storage tanks by previous research.rs. In th.s paper a numerical model is developed based on incompressible and inviscid fluid motion for th. liquid slosh.ng ph.nomenon. Th. coupled BEM-FEM is used to solve th. governing equations and nonlinear free surface boundary conditions. Th. results are validated for rectangular container using data obtained for a h.rizontal periodic sway motion. Using th. results of th.s model a new arrangement of trapezoidal sh.pes with.quadratic sidewalls is suggested for tanker sh.p storage panels. Th. suggested geometric sh.pe not only h.s a maximum surrounded tank volume to th. constant available volume, but also reduces th. slosh.ng effects more efficiently th.n th. existing geometric sh.pes.

Th.oretical analysis of th. dynamic beh.vior of cavitating vortices requires knowledge of th. velocity distribution in th. vortex core. For th.t reason an existing similarity model for slender axisymmetric non-cavitating vortex cores h.s been extended with.th. viscous boundary conditions for a cavitating vortex. Cavitating similarity solutions exist for a vortex of wh.ch.both.core diameter and circulation grow with.th. square root of th. axial coordinate. Results for th.s model are presented for varying cavitation numbers and Reynolds numbers. It is sh.wn th.t viscosity may h.ve a significant influence on th. velocity distribution around a cavitating vortex.
