This article proposes an effective methodology for the fluid-dynamic design optimization of sliding spool a hydraulic proportional directional valve: goal is minimization flow force at prescribed rate, so as to reduce required opening while keeping operation features unchanged. A full three-dimensional model field within valve employed accurately predict acting on spool. theoretical analysis, based both axial momentum equation and simulations, conducted define parameters, which need be...
The escalation of the COVID-19 outbreak has significantly increased research into transmission airborne infectious diseases in indoor settings, underscoring urgent necessity for affordable and efficient methods air disinfection. aim present work is development a complete framework based on designed experiments exploring optimizing bioaerosol removal inactivation efficiency novel disinfection device. This device combines aerodynamic effect three-dimensional vortex structure with UV-C...
An analysis is presented of a complex set data on the strength steels as function chemical composition, heat treatment, and test temperature. The represent special class designed to resist deformation at elevated temperatures (750–950 K) over time periods in excess 30 years, whilst serving hostile environments. aim was compare two methods, neural network based Bayesian formulation, genetic programming which are formulated an evolutionary procedure. It found that present context, able more...
This paper illustrates an automatic multi-objective design optimization of a two-dimensional airfoil cascade row having finite number airfoils. The objectives were to simultaneously minimize the total pressure loss, maximize aerodynamic loading (force tangent cascade), and airfoils in row. constraints were: fixed mass flow rate, axial chord, inlet exit angles, blade cross-section area, minimum allowable thickness distribution, lift force, trailing edge radius. means that entire shape was...
The resilience of transport systems, facing natural or man-made disruptions, has been widely discussed in literature terms recovery capabilities concerning infrastructures, suggesting solutions to provide users an acceptable level service along the interrupted network. However, context Covid-19 outbreak, disruption stressed systems not on supply side but rather at organizational for providers. Indeed, sudden and drastic decrease due restrictions imposed by governments limit pandemic spread...

Abstract Numerical flow analysis in turbomachinery is an indispensable tool for water turbines design. Following the design of axial runner, energetic and cavitation characteristics can be predicted using numerical method. In this paper it described how multiobjective genetic algorithm aids human decision best solution, based on objective functions obtained by analysis. Theoretical empirical knowledge procedure enables to start optimization with good initial geometry. A very effective...
This paper describes an application of Robust Design methodology in the transonic airfoil design. It has been observed that, minimizing drag at a single design point (Mach number and angle attack fixed), it is possible to find solutions characterized by poor offdesign performances (over-optimizing problem). For this reasons, stability inside range operative conditions important objective Once are defined (range Mach attack), Multi Objective approach ne eded; particular, two objectives be...
Selecting the best scenario of intervention to improve functioning complex systems represents a troublesome task both for public and private decision makers, since it requires deployment appropriate analysis evaluation tools. In case intermodal transport systems, complexity is given by execution different types activities using various resources, presence several actors operating in same environment with diverse goals. this paper, an integrated approach assess design alternatives regarding...
Liquid foam flows in a Hele-Shaw cell were investigated. The plug flow obtained for monodisperse is strongly perturbed the presence of bubbles whose size larger than average bubble by an order magnitude at least. large migrate faster mean above velocity threshold which depends on its size. We evidence experimentally this new instability and, case single bubble, we compare with prediction deduced from scaling arguments. In bidisperse foam, attractive interaction between induces segregation...
