A fluid turbine apparatus which is able to increase the fluid velocity and consequently increase the rotation speed of the fluid turbine.

Alternatively, fluid velocity filters are used.

The fluid velocity sensor can be arranged in a uni-directional or bi-directional fluid flow configuration.

This effect is enhanced with increased fluid velocity.

A less viscous fluid will have a relatively greater velocity and centrifugal force than a more viscous fluid.

Examples of fluid properties based on which the device can direct fluid include fluid density, fluid velocity, fluid viscosity, and Reynolds number of the fluid flow.

The systems and methods may be used to display the actual fluid velocity or a proportionate fluid velocity for a respective streamline at predetermined incremental time steps,

In another feature of this invention, cryogen velocity is derived from a self-pressurized dewar containing a saturated cryogen.

The fluid velocity inducer (50) is located in the entry stream path of the fluid inducing a velocity thus reducing or eliminating the stagnation zone and improving the cooling of the core.

A detection unit (180) includes a fluid direction detection unit, a fluid velocity detection unit, a central shaft speed detection unit, and a central shaft position detection unit.

The invention solves the problem of stagnation by application of a fluid velocity inducer (50).

The fluid delivery system preferably comprises fluid circulation means having an intake opening for the fluid and vanes that assist in increasing fluid velocity and reducing turbulent flow.

A fluid measurement system and method for determining distributed measurement of a fluid type and a fluid velocity in a wellbore, pipeline or other conduit in which fluid is moving.

The apparatus (3) improves the fluid flow characteristics by minimizing or eliminating fluid velocity jets and/or other turbulence which can disturb the downstream particle bed.

Fluid velocity: Driving it toward the axis of rotation—“counterflow elutriation.
