The free-vortex flow, which occurs inside the rotating cavity between the disc and cover-plate, is controlled principally by the pre-swirl ratio, β p: this is the ratio of the tangential velocity of the air leaving the nozzles to that of the rotating disc. Computed values of the tangential velocity are in good agreement with measurements, and ...

A uniform disk rotating with constant angular acceleration covers 50 revolutions in the first five seconds after the start. Calculate the angular acceleration and the angular velocity at the end of five seconds. Physics. Q3. A disc rotates with a uniform angular acceleration of 2.0 rad/s 2 about its axis.

Disc Pumps. Without an impeller, piston, diaphragm or screw, the unique pumping mechanism of the disc pump is based on the effect of a boundary layer and viscous drag principle, which produces a pulsation-free laminar flow. This technology creates a low-to-no maintenance system by minimizing contact between the pump and the raw material being ...

A waist-twisting disc is a novel piece of home exercise equipment with a rotating platform. The bottom disc is static, and the top disc rotates on top of the bottom disc. To operate it, you stand or sit on it and rotate your torso so that your shoulders and chest go in one direction and your hips and knees go in the opposite direction.

As an example, those in the quarrying industry generally are not worried about most aspects of the valve supply providing it performs to specification and is durable, whereas at the other extreme the food and in particular the pharmaceutical industry are necessarily much …

Synchronous speed is the speed of rotation of the magnetic field in a rotary machine, and it depends upon the frequency and number poles of the machine. The induction motor always runs at speed less than its synchronous speed. The rotating magnetic field produced in the stator will create flux in the rotor, hence causing the rotor to rotate. Due to the lag between the flux current in the rotor ...

The rotating cores predicted by Batchelor were not observed in experiments performed by Stewartson (5).Experiments were conducted on discs of 150mm diameter, at rotational speeds of up to 250 rad/s (Re ϕ ≈09.4 × 10 4), and the rotating cores were not observed. Figure 2 illustrates the Stewartson-type flow structure for rotor-stator and contra-rotating disc systems.

Swirl Flow Around a Rotating Disk. Application ID: 616. Swirl flow is an application that involves steady rotational flow around an axis. Rather than modeling this process in 3D, COMSOL Multiphysics provides a 2D axisymmetric interface where the flow in the rotational direction is still included in the equations.

BELOIT, Wis., Oct. 5, 2021 — Regal Beloit Corporation, a global leader in the engineering and manufacturing of electric motors and controls, power generation products and power transmission components, today announced it has completed the merger with Rexnord Process and Motion Control (PMC) to become Regal Rexnord Corporation (NYSE: RRX).

The rotating biological contactor (RBC) has been used in Europe for many years to treat both municipal and industrial waste waters. RBC's produce a high quality effluent. RBC's are fixed-film reactors similar to bio filters in that organisms are attached to support media. The support media of RBCs are slowly rotating discs that are partially […]

For a rotating disc gas-liquid contactor a relationship has been derived between the amount of liquid entrained by a disc and its rotational velocity: where δ is a mean film thickness on the disc ...

The flow due to a disk rotating in its own plane has been investigated theoretically by von Kármán, Goldstein, and others, but little has been published on the heat transfer. For laminar conditions theoretical solutions have been given by Millsaps & Pohlhausen and by Wagner, but for conditions when the flow is turbulent over the outer part of ...

Re: Monitoring an old electricity meter (rotating disc) « Reply #13 on: January 10, 2016, 04:49:53 pm ». - You could add a led to give a constant ambient light. - You could measure the analog voltage/current of the detector with the microcontroller and do some simple [adaptive] filtering before detection.

4.4.1 The Rotating Disc Consider a thin disc rotating with constant angular velocity, Fig. 4.4.1. Material particles are subjected to a centripetal acceleration a r 2 r . The subscript r indicates an acceleration in the radial direction and the minus sign indicates that the particles are accelerating towards the centre of the disc. Figure 4.4 ...

Disentangling the stellar populations in the counter-rotating disc galaxy NGC 4550. In order to try and understand its origins, we present high-quality long-slit spectral observations of the counter-rotating stellar discs in the strange S0 galaxy NGC 4550. We kinematically decompose the spectra into two counter-rotating stellar components (plus ...
