Fluid Kinematics
Описания эйлеровых и лагранжевых течений
Fluid flow can be described using two main approaches: the Eulerian and Lagrangian methods.
The Eulerian method measures fluid properties like pressure, ...
Введение в типы потоков
Flows can be categorized based on dimensionality. In one-dimensional flow, properties like velocity and pressure change along a single direction, as seen ...
Линии тока, полосы и контуры
Consider water flowing steadily through a curved pipe. The direction of flow inside the pipe can be visualized using streamlines.
A streamline represents ...
Регулировка громкости и системных представлений
A control volume is a defined region in space where interactions involving mass, energy, or momentum are analyzed.
Consider water flowing through a pipe. ...
Скорость и ускорение в установившемся и нестационарном потоке
Consider a fluid particle moving along a pathline in a flow. The particle's velocity is denoted by the function of its location and time.
Now, the ...
Теорема Рейнольдса о транспорте
Consider a fluid in motion. The Reynolds transport theorem provides the relationship between the time rate of change of an extensive property in a system ...
Пример конструкции: Протекание через огнетушитель
A fire extinguisher uses pressurized water to generate a powerful stream through a nozzle.
The water inside is stored at a much higher pressure than the ...
