So for example, if I were to pass a vortex through a Venturi tube, would the rotational velocity increase due the vortex being closer to it's axis, or would the increase in frictional forces cancel it out?
Constant, like the coefficient of friction mew, between the streamlines. Cos the more input energy you use to induce a faster vortex, the larger the frictional forces...right?
So are you saying that the friction between the streamlines are somewhat constant, and more input energy is needed for a narrow Irrotational vortex...?
Nah, I'm referring to general physics, not the space time stuff.
Like for example, when you whirl your hand in a bucket of water, you'll create an Irrotational vortex right? And the explanation provided by
Wikipedia first says that the fluid's speed in an Irrotational vortex is inversely...
So I was reading about Vortices in Wikipedia, when I stumbled upon the explanation about Irrotational Vortices.
It states there that in Irrotational vortices, the fluid's flow velocity u, is inversely proportional to the distance r, from the vortex's axis.
Then, at the end of the...
The larg horizontal turbines use aerodynamic lift that strongly depends on the angle of attack and the resulting vectors of motion. Any manipulation of the airstream changes this relationship, and it's alway down hill. Shrouding of any kind limits the potential energy, the bucket effect.
I guess...
I guess you're right, I carried out an experiment with this wind tunnel I built: , powered by a desk fan: . The anemometer I got, is this model: with a propeller typed-blade. And is located in the blue cuboid casing between the 2 pyramids.
So it works by using the desk fan, located at the red...
Nah, I'm asking about rotational airflow being directed at a normal wind turbine, would it's rotational force generate from rotation from the wind turbine?
I'm working on a project now and I'd like to know which type of airflow would power a turbine faster/better straight or rotational?
Or will rotational airflow even have any effect on the turbine...?
P.S. When I say rotational airflow, I mean circular airflow that rotates in the same direction...
I'm currently looking for an efficient water splitting water catalyst for my Chemistry project. Titanium Dioxide is the popular one, as it's cheap and abundant.
However, TiO2 is only most efficient when shined by UV light, not visible light ---> Which accounts for more than half of solar...
I'm currently working on a project about wind speeds, and have come across a roadblock due to my limited knowledge... So I really hope you guys can help me out.
When you light a campfire or candle, the heat from the flames cause the air around it to rise, which leaves a "vacuum" for colder...
