Abstract

Polyhedral  heteroboranes in particular dicarba-closo-dodecaboranes(12) and their organic derivatives have been the subject of intense research for over 40 years due to their unique chemical and physical properties. The initial attraction to dicarba-closo-dodecaboranes(12) In the medicinal chemistry research, was a result of their high boron content and stability to catabolism, which are important criteria for cancer therapy, such as BNCT (boron neutron capture therapy) agents. The coordination compounds of the platinum group metals have also received large interest for their potential application as chemotherapeutic agents, since  cis-diamminedichloroplatinum(II), cisplatin, has been reported to have  capability as tumor inhibitor. Hence, applications can be envisioned for related  cis platinum complexes. Complex of  cis-rac-[PtCl2{1,2-(PRCl)2C2B10H10}] (R=Ph,  tBu, NEt2, NPh2) have been synthesized by employing known carbaborane based phosphine ligands of clorophoshino-closo-dodecaborane , with complex of  cis-[PtCl2(COD)] (COD = 1,5-cyclooctadiene) in an N2-atmosphere. The obtained complexes possess expected structure configuration, namely  cis-rac.  The characterization of the complex has been carried out using 1H,  31P,  13C and  11B-NMR (Nuclear Magnetic Resonance), X-ray of single crystals, elemental analysis, IR (infra red) and mass spectroscopy (MS). The  31P{1H} NMR spectra of all the platinum complexes distinctly show the typical platinum satellites which are attributed to 31P-195Pt-coupling, in which the 31P{1H} NMR spectrum exhibits three lines with an intensity ratio of ca. 1:4:1. The structure of the platinum complexes consists of a slightly distorted square-planar coordination sphere, in which the platinum  atom is bonded to two chlorides and two phosphorus atoms of the chelating carbaboranylphosphine. Thus the platinum atoms exhibit the coordination number four, which is preferred in platinum(II) complexes.

Abstract

This paper presents the results obtained from the application of computational fluid dynamics (CFD) to modelling the flow field of a Lapple cyclone and to optimizing the cyclone based upon its geometrical parameters. A pre-processor software GAMBIT was employed to set up the configuration, discretisation, and boundary conditions of the cyclone.  The characteristics of the cyclone being studied was 0.2 m in diameter, receiving a gas flow rate of 0.1 m3/s with a particle mass loading of 0.01 kg/m3.  A commercial CFD code FLUENT 6.2.16 was employed to simulate the flow field and particle dynamics in the cyclone. The objective of this research was to investigate the performance of a number of turbulence models on the prediction of the flow field, collection efficiency and pressure drop in the Lapple cyclone. A number of five turbulence models under Reynolds Averaged Navier Stokes (RANS) category, including Spallart-Allmaras, standard k-ε model, RNG k-ε model, standard k-ω model, and Reynolds Stress Model (RSM) were examined in the simulation of the flow field and particle dynamics inside the cyclone. A validation of all calculation was performed by comparing the predicted results in terms of axial and tangential velocities, efficiency and pressure drop against experimental data of a Lapple cyclone taken from literature. The results of the investigation show that out of five turbulence models being tested, the RSM presented the best predicted results. The predictions of axial and tangential velocities as well as cyclone efficiency by this model are in excellent agreement with the experimental data.  Although the pressure drop in the cyclone is under-predicted, the RSM predictions are far better than those of other model. Other turbulence models are over-predicted and under-predicted the axial and tangential velocity, respectively.  With respect to efficiency and pressure drop of the cyclone, other models are capable of following the trend of the experimental data but they failed to agree with the experimental values.  These results suggest that the RSM is the most suitable turbulence model to represent the flow field and particle dynamics inside a cyclone gas-solid separator.

Abstract

This paper presents the results obtained from the application of computational fluid dynamics (CFD) to modelling the crosswind effect on a turbulent non-premixed flame. A pre-processor software GAMBIT was employed to set up the configuration, discretisation, and boundary conditions of the flame being investigated.  The commercial software Fluent 6.3 was used to perform the calculations of flow and mixing fields as well as combustion. Standard k-ε and eddy dissipation models were selected as solvers for the representation of the turbulence and combustion, respectively.  The results of all calculations are presented in the forms of contour profiles.  During the investigation, the treatment was performed by setting a constant velocity of fuel at 20 m/s with varied cross-wind velocity and by keeping the cross-wind velocity constant at 1.1 m/s with varied fuel velocity.  The results of the investigation showed that the standard k-ε turbulence model in conjunction with Eddy Dissipation Model representing the combustion was capable of producing reliable phenomena of the flow field and reactive scalars field in the turbulent non-premixed flame being investigated. Other results of the investigation showed that increasing the velocity of the crosswind, when the fuel velocity was kept constant, significantly affected the flow field, temperature and species concentrations in the flare flame. On the other hand, when the velocity of the fuel was varied at the constant crosswind velocity, the increasing velocity of the fuel gave positive impact as it enabled to counteract the effect of crosswind on the flare flame

Abstract

This paper presents the results obtained from the application of both computational fluid dynamics (CFD) Fluent 6.3 and Design Expert codes to modelling and optimizing a gas-solid cyclone separator based upon its geometrical parameters. A pre-processor software GAMBIT was employed to set up the configuration, discretisation, and boundary conditions of the cyclone.  A commercial CFD code FLUENT 6.3 was employed to simulate the flow field and particle dynamics in the cyclone. The optimization study was performed under either a constant gas inlet flow rate of 0.075 m3/s or a constant inlet gas velocity of 18 m/s. A response surface methodology with three levels (-1, 0, and +1) was employed as the experimental design. Independent variables to be optimized include the ratio of inlet gas width to diameter of the cyclone, W/D, the ratio of conical length to diameter, Lc/D and the ratio outlet diameter to cyclone diameter De/D. The response variables of collection efficiency and pressure drop were correlated in the forms of quadratic polynomial equations. The simultaneous optimization of the response variables has been implemented using a desirability function (DF) approach, computed with the aid of Design Expert software.  The results of investigation showed that at constant flow rate, the following optimum ratios of W/D =0,28, Lc/D =1,5,  and De/D =0,52 were obtained to give a collection efficiency of 90% and a pressure drop of 155 Pa. At the constant inlet gas velocity, the following optimum ratios of W/D =0,25, Lc/D =1,5,  and De/D =0,57 were obtained to give a collection efficiency of 90% and a pressure drop of 190 Pa. This findings indicate that gas inlet treatment at either constant flow rate or constant inlet gas velocity does not produce significant difference on the collection efficiency, but does give significant influence on the pressure drop.
