Journal of Basic and Applied Research International, Page 283-289

The colorless solid, phthalic anhydride is an important industrial chemical, especially for the industrial scale production of plasticizers for plastics manufacturing. One of the most important approaches to obtain this widely used material in the production of dyes is via catalytic oxidation of ortho-xylene. The current study is aiming to simulate the phthalic anhydride production scale process employing computational fluid dynamics (CFD). Two types of reactor are considered: fixed and fluidized beds. Representative equations including kinetics, continuity, mass transfer, energy, momentum and pressure drop are solved simultaneously. Subsequently, the effects of inlet temperature on conversion percentage of phthalic anhydride production process is observed in detail. The ultimate goal of the investigation for the involved reactions which are pyrogenic, is controlling the peak temperature of the reactor. Our investigation shows that conversion percentage of phthalic anhydride in fluidized bed is much higher in compared to fixed bed. Furthermore, the results show that undesirable production conversion of fluidized bed is less proportional to fixed bed production scale.

A FEM APPROACH FOR DYNAMIC MOTION AND CONTROL OF ELECTROSTATIC MICROMOTORS

MOHAMMAD JAVAD NAVARDI, AMIR ATA YADGHAR, BEHNAZ BABAGHORBANI, ABBAS KETABI

Journal of Basic and Applied Research International, Page 307-322

A quasi-static approach based on two-dimensional Finite Element Analysis (FEA) is described to calculate the position and speed of the rotor of Variable Capacitance Micromotor (VCM). FEA is performed to compute the overall capacitance of the rotor-stator combination when the stator is excited symmetrically. A continuous curve is fit to energy-angle ‎points by the spline interpolation technique that is very effective for data fitting. Thus the energy vs. angle function is obtained and the torque is calculated by the ‎partial derivative of energy vs. angular displacement. A quasi-static approach is then adopted to the operation model of the entire micromotor. Also a new speed control method is presented which the rotor is rotated based on the torque estimated by extrapolating the earlier FEA result for a single stator pole. It can enable a sufficient fast and accurate way to dynamic simulation and control of VCM.

Journal of Basic and Applied Research International, Page 358-367

The quality of the roots of Securinega virosa (Euphorbiaceae) commonly marketed in Ghana for medicinal purposes needs to be assured through standard quality control procedures. This work has isolated and characterized a biomarker to be used in assessing the quality of products and herbal preparations containing the roots of Securinega virosa. Using column chromatography of 20 g ethanolic roots extract; 0.02% w/w biomarker was obtained and characterized by melting point determination, UV-Vis, IR, 1D and 2D NMR spectroscopic analysis and comparison to reported literature. The biomarker was identified as Bergenin. A RP-HPLC method has been developed and validated for the quality control of S. virosa root preparations with Bergenin as standard. The most appropriate resolution was attained by a gradient elution of methanol: 0.05% v/v trifluoroacetic acid in water using Waters Bondapak C18 (3.9×300 mm, 5 μ) column at a flow rate of 1.0 ml/min and a wavelength of 220 nm. The retention time of the biomarker was found to be 14.20 ± 0.01 mins. The method was subjected to ICH guidelines for validation and showed a good linearity with a correlation coefficient (r) of 0.9993. The LOD and LOQ were found to be 15.23 mg/L and 46.16 mg/L respectively. Tolerable levels of accuracy, precision, specificity and robustness were observed. The developed RP-HPLC method estimated 0.465%w/w Bergenin in the roots of S. virosa and may therefore be employed in the quality control of product containing roots of S. virosa.

Journal of Basic and Applied Research International, Page 301-306

Cold fluid was flowed through pipeline whereas hot fluid was flowed through the side from side in a side-tee pipeline formation. Experiments were carried out reading temperature of downstream flow for varied velocities. Computational fluid dynamics package was used for geometry creation, mesh generation, and defining the control volume for computations according to the experimentations for varied velocities. Results validated the model and scale up of the geometry was made whereas the diameter ratio constant was kept constant for creation of scale-up geometry. For the scale-up geometry for varied velocities, computations are performed too and heat transfer mixing position is located for both cases for various velocities. For scale-up geometry, it is plotted that downstream heat transfer mixing position is lengthily distanced. Earlier mixing is attained for lower velocities comparatively.

GLOBAL AND LOCAL EXERCISES OF MESH REFINEMENT OF CONTROL VOLUME MODELS WITHOUT REMESHING

ZAHID H. I. KHOKHAR

Journal of Basic and Applied Research International, Page 348-357

Liquid-water is introduced at different temperature from side and upstream in a tee pipeline domain. The operation is simulated after construction of control volume and triangular tetrahedral mesh generations are performed. Smaller global fine remeshing hung the work station and for this case, without remeshing, the grid is refined locally at jet region. Effects of the region adaption are shown and swapping is executed to improve computation. Profiles along centerline of side jet and profiles along the centerline of the pipe, away from the jet, are almost identical, however, for the jet zones the profiles showed certain differentiation. An increase in the number of cells results in a larger increase in the unit time required for convergence from machine to machine. The use of the finest refinement is recommended at the gradients.

Journal of Basic and Applied Research International, Page 376-385

The current paper aimed to conceptually underline the prediction of entrepreneurial intentions of female students in Egypt. The paper asserts through prior scholarly evidence that social support and entrepreneurial self-efficacy can have a massive value towards enhancing females’ entrepreneurial intentions. The paper sheds light on how social support means may allow an individual to increase willingness to engage in entrepreneurial activities mainly for females. Accordingly, the paper also sheds light on why it is essential to boost individual confidence in themselves (efficacy) to further these intentions for entrepreneurial willingness. In addition, throughout the literature, it has been identified that entrepreneurship education is one of the most important factors that steer entrepreneurial intention towards starting a venture and considered as a key area in entrepreneurship’s domain. In this sense, the paper further outlines that there is a potential of the significant moderating role of Entrepreneurship Education on these relationships between Social Support and Entrepreneurial Self-efficacy on Female entrepreneurial Intention. The paper presents a critical reflection, debate and arguments over the topic for future scholars aiming to work on developing entrepreneurial intentions particularly among the Egyptian female students who are the actual business leaders of tomorrow.
