Determination of optimal parameters of a moving wall on airfoil

A problem is posed and solved on determining the optimal parameters of a moving wall installed on the airfoil surface to prevent the boundary layer separation. As the wall parameters, its initial and final position and motion velocity are taken. To solve the problem, the optimization methods with penalty functions are used. The conclusions were drawn on selecting the efficient parameters of the moving wall in terms of the minimum of energy expenditure and friction drag. © 2012 Allerton Press, Inc

Innovative projects for the processing of industrial waste

© Medwell Journals, 2016.The study deals with innovative projects for the processing of industrial waste. Industrial waste has become a pressing issue for the big cities and their disposal is an important task of the government. At the same time, stocks of raw materials are reducing and the cost of their production and transportation is increasing. That is why, the task is assigned to establish a sustainable environmental waste management system in Russia. Environmentalists need new and innovative equipment for the collection, transportation and reduction of industrial waste as well as innovative technologies for its processing. Innovative projects analyzed in the study solve the problem of industrial waste disposal which has economic and social benefits

Modern principles of financial services markets regulation as a response to the financial and economic crisis of 2008

© MCSER-Mediterranean Center of Social and Educational Research. The financial and economic crisis of 2008 revealed lack of tools and inefficiency of methods used by regulators of leading states to predict and prevent crisis of global proportions. In this regard, national and supranational regulators are trying to introduce new principles for regulation of financial services markets, based on the philosophy of macro-prudential regulation. The paper presents a comparative analysis of institutions and methods of regulation in the USA, UK and European Union. The authors critically analyze the effectiveness of new models of regulators, questioning the benefits of new ones in comparison with previous. They emphasize the necessity to reform not only institutional structure of regulators but methodology of their activities too, as well as, the absence of universal prescription of reforms, coming to conclusion, that each country must choose its own, based on their legal traditions, regulatory system

Project risks’ management model on an industrial entreprise

© Canadian Center of Science and Education. The article proposes complex model of project risks’ management on an industrial enterprise, including interrelation of work stages in risk management, project risks’ evaluation and management methods and instruments; and an integrated index as an element of risks analysis technique. Project risk analysis and evaluation process takes one of the major places in procedural aspect. Risk management begins with the quality risk analysis where risks are identified and grouped. Results of quality risk analysis are used for the subsequent quantitative risk analysis which includes their evaluation in three key parameters: probability of a risk event, level of expected losses, limits of manageability of risks. Integrated index for risks’ analysis and evaluation developed by the author considers risks’ dual nature, probabilities balance, realization consequences and risks’ manageability. The function of this integrated index is identification of the project risks which can be influenced the most. Based on the calculation of integrated indexes of the identified project risks the decision on primary management for the risks with greater integrated indexes is made. The main procedure after the quantitative risk analysis of the risk management stage is to choose the risk management method and its subsequent application. It is necessary to analyze and generalize risk management activity efficiency, risk factors and uncertainty in the project finale. All the integrated information goes to an organization databank for further use

Influence of pulsating flow on dispersion in helically coiled tubes and coiled flow inverters

Narrow Residence Time Distribution (RTD) is a desirable characteristic for many chemical engineering processes. However, when flow devices operate at low Reynolds number (characteristic for micro and millifluidic devices), significant fluid dispersion can occur. Narrowing RTD, while maintaining long space time, is currently a challenge. In this work, we addressed this by a combination of passive and active mixing techniques similar to those found in arterial flow. In the biomedical literature, plug flow is often assumed due to low axial dispersion in blood flow [1]. By reviewing this literature, we identified that the reduction in axial dispersion in arteries can be attributed to two factors, curvature of the blood vessels (Dean number in arteries reaches 260) [2] and pulsation of the flow [3]. Flow in curved geometries leads to formation of Dean vortices due to centrifugal force and is a well-established passive mixing technique [4]. At the same time, the introduction of a periodic variation in the flow rate (later on referred to as pulsation for simplicity) is an active technique which was first described in the fluid dynamics literature in the early 1960s [5]; however, it is yet to be utilized to its full potential within the millifluidic community. In process engineering, each of these techniques has been shown separately to have a positive effect and here we investigate the effect of utilizing both of these techniques simultaneously for narrowing RTD. The effect of two key dimensionless pulsation parameters, amplitude ratio (, dimensionless amplitude of pulsation) and Strouhal Number (St, dimensionless frequency of pulsation), on RTDs was studied in Helically Coiled Tubes (HCTs) and Coiled Flow Inverters (CFIs). Additionally, the contribution of tube elasticity was also considered, since arteries are less rigid than the hard walled channels typically used in chemical engineering processes. An experimental system was developed to conduct RTD experiments via step injection of tracer at the tube inlet and measurement of tracer concentration via UV-Vis spectroscopy at the tube outlet. Experiments without pulsation were also conducted for comparison. The results showed that in the presence of pulsation narrower RTDs are achievable. Furthermore, both increase in amplitude and frequency of pulsation have a positive effect on reducing dispersion. Separately, pulsation and curved geometries could achieve a maximum reduction of vessel dispersion number (dimensionless parameter that measures the extent of axial dispersion) from 190 to 110 and 125, respectively. When tube curvature and flow pulsation are combined, the vessel dispersion number was reduced by an order of magnitude (from 190 to 20). Numerical simulations supported the experimental results and showed that in the presence of pulsation there is a significant enhancement of radial mixing. Further consideration included the effect of tube elasticity on RTD. It was found that reduction in the RTD width in a harder material is more pronounced than that in a softer material. Overall, the results show a promising technique for reducing the RTD, which can benefit a variety of fields including process intensification, particle synthesis and continuous manufacturing.
