Torsional buckling and postbuckling of columns made of aluminium alloy
PublicationThe paper concerns torsional buckling and the initial postbuckling of axially compressed thinwalled aluminium alloy columns with bisymmetrical crosssection. It is assumed that the column material behaviour is described by the Ramberg–Osgood constitutive equation in nonlinear elastic range. The stationary total energy principle is used to derive the governing nonlinear differential equation. An approximate solution of the equation...

Electromechanical shear buckling of piezoelectric nanoplate using modified couple stress theory based on simplified first order shear deformation theory
PublicationThis paper studies the electromechanical shear buckling analysis of piezoelectric nanoplate using modified couple stress theory with various boundary conditions.In order to be taken electric effects into account, an external electric voltage is applied on the piezoelectric nanoplate. The simplified first order shear deformation theory (SFSDT) has been employed and the governing differential equations have been obtained using...

Modeling the impact of discretizing rotor angular position on computation of fieldoriented current components in high speed electric drives
PublicationModern drives consist of alternating current electric motors, and the fieldoriented control (FOC) of such motors enables fast, precise, and robust regulation of a drive's mechanical variables such as torque, speed, and position. The control algorithm, implemented in a microprocessor, requires feedback from motor currents, and the quality of this feedback is essential to a drive's control properties. Motor phase currents are sampled...

Nuclear Power Plant Steam Turbine  Modeling for Model Based Control Purposes
PublicationThe nature of the processes taking place in a nuclear power plant (NPP) steam turbine is the reason why their modeling is very difficult, especially when the model is intended to be used for online optimal model based process control over a wide range of operating conditions, caused by changing electrical power demand e.g. when combined heat and power mode of work is utilized. The paper presents three nonlinear models of NPP steam...

Expedited constrained multiobjective aerodynamic shape optimization by means of physicsbased surrogates
PublicationIn the paper, computationally efficient constrained multiobjective design optimization of transonic airfoil profiles is considered. Our methodology focuses on fixedlift design aimed at finding the best possible tradeoffs between the two objectives: minimization of the drag coefficient and maximization of the pitching moment. The algorithm presented here exploits the surrogatebased optimization principle, variablefidelity computational...

Thermal selfaction effects of acoustic beam in a vibrationally relaxing gas
PublicationThermal selfaction of acoustic beam in a molecular gas with excited internal degrees of molecules’ freedom, is studied. This kind of thermal selfaction differs from that in a Newtonian fluid. Heating or cooling of a medium takes place due to transfer of internal vibrational energy. Equilibrium and nonequilibrium gases, which may be acoustically active, are considered. A beam in an acoustically active gas is selffocusing unlike...

Problem of proper decomposition and initialization of acoustic and entropy modes in a gas affected by the mass force
PublicationThe relations connecting perturbations specific for acoustic and entropy modes in an accelerated fluid or in a fluid affected by constant mass force, are derived. They allow to decompose the total vector of perturbations and the overall energy into acoustic and nonacoustic parts uniquely at any instant. In order to do this, three quantities are required, for example total perturbations in entropy, pressure and velocity. The evaluations...

Study of free convective boundary layer of isothermal lateral surface of axisymmetrical horizontal body
PublicationPrzedstawiono rozwiązanie równań NavieraStokesa i FourieraKirchhoffa we współrzędnych tau i sigma. Pierwsza jest styczną a druga normalną do konwekcyjnych linii prądu, wzdłuż jakich porusza się ogrzany od powierzchni płyn. Wynik w postaci równania na grubość warstwy przyściennej zweryfikowano dla granicznych przypadków ciała obrotowego o poziomej osi symetrii (stożka poziomego i kołowej pionowej płyty).
