The top half of casings is removed, showing two rotors. Axial steam turbines still had not exceeded 50% efficiency by that time, and so civilian ships chose to utilize diesel engines due to their superior efficiency.Tesla's design attempted to sidestep the key drawbacks of the bladed axial turbines, and even the lowest estimates for efficiency still dramatically outperformed the efficiency of axial steam turbines of the day. It is referred to as a bladeless turbine.The Tesla turbine is also known as the boundary-layer turbine, cohesion-type turbine, and Prandtl-layer turbine (after Ludwig Prandtl) because it uses the boundary-layer effect and not a fluid impinging upon the blades as in a conventional turbine.

"Tesla: Master of Lightning." Under load, the number of rotations drops and the spiral becomes progressively shorter.Efficiency is a function of power output. EV World. The guiding idea for developing Tesla turbine is the fact that in order to attain the highest efficiency, the changes in the velocity and direction of movement of fluid should be as gradual as possible.A Tesla turbine consists of a set of smooth disks, with The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. "Nikola Tesla's Disk Turbine" http://www.frank.germano.com/teslaturbine2.htmHait, John. In standard BST the steam has to press on the blades in order for the rotor to extract energy from the steam speed, due to the difference between the relative speed of the steam and the blades.

Nearby is a bladeless waterwheel turbine of Tesla's design. However, the best economic results in the development of power from steam by the Tesla turbine will be obtained in plants especially adapted for the purpose.

This translates to needing to increase the number of disks as the flow rate increases. Maximum efficiency comes in this system when the inter-disk spacing approximates the thickness of the boundary layer, and since boundary layer thickness is dependent on viscosity and pressure, the claim that a single design can be used efficiently for a variety of fuels and fluids is incorrect. Minor departures from the turbine, as may be dictated by the circumstances in each case, will obviously suggest themselves but if it is carried out on these general lines it will be found highly profitable to the owners of the steam plant while permitting the use of their old installation. Reportedly, the efficiency of the Tesla turbine drops with increased load. Pure Energy Systems News.

Under light load, the spiral taken by the fluid moving from the intake to the exhaust is a tight spiral, undergoing many rotations. The steam enters at the periphery, and flows in spiral paths to exhaust at the center of the disks. Wind turbines, like these in Palm Springs, Calif., are examples of other turbines being used to generate electricity. In TT, considering that there are no blades to be impacted what is the mechanism of this energy of reaction to materialize.

The oil crisis drove the majority of new civilian vessels to turn to diesel engines.

Tesla's patents state that the device was intended for the use of Today, many amateur experiments in the field have been conducted using Tesla turbines which use One proposed current application for the device is a Applications of the Tesla turbine as a multiple-disk centrifugal In Tesla's time, the efficiency of conventional turbines was low because turbines used a direct drive system that severely limited the potential speed of a turbine to whatever it was driving. The tesla turbine is a nonconventional promising technology that is yet to be fully researched and optimized. The improvement in steam technology gave the U.S. Navy aircraft carriers a clear advantage in speed over both Allied and enemy aircraft carriers, and so the proven axial steam turbines became the preferred form of propulsion until the 1973 oil embargo took place. Despite the highly efficient bladeless wind turbine being first invented over 100 years ago by the late Nikola Tesla, humanity's first attempt at harvesting wind energy involved using wind turbines with 3-blades, which proved to be visually obstructive, inefficient and perilous to both humans and wildlife.

When the rotor is not under load the relative speeds between the "steam compressed spirals" (SCS, the steam spirally rotating between the disks) and the disks is minimal.

For example, the turbine on the As time went on, competing Axial turbines became dramatically more efficient and powerful, a second stage of reduction gears was introduced in most cutting edge U.S. naval ships of the 1930s. Again, the propelled machine a great torque is always desirable, this calling for an increased number of disks and smaller distance of separation, while in the propelling machine, for numerous economic reasons, the rotary effort should be the smallest and the speed the greatest practicable.Let now investigate the Tesla Turbine (TT), and shortly technically every Blade Steam Turbine (BST) first, in respect to the Newton's 3 Law of Motion (N3LM).

Each rotor consists of 25 disks 3/8-inch thick by 18 inch diameter. That belt is most dense, pressurized, in the periphery as it pressure, when the rotor is not under load, will be a notch less, then the steam pressure. Here we have to note that fluids start to behave like solid bodies at high relative velocities, and in TT case, we also have to take in consideration the additional pressure.
