Creating Wheel-Thrown Potteries in Digital Space
This paper introduces a novel technique to create digital potteries using certain simple-yet-efficient techniques of digital geometry. Given a digital generatrix, the proposed wheel-throwing procedure works with a few primitive integer computations only, wherein lies its strength and novelty. The created digital surface is digitally connected and irreducible when the generatrix is an irreducibl...
متن کاملModelling a Tidal Turbine in Unsteady Flow
A brief review of the literature is provided on the characteristics of marine currents and the approaches used for simulating tidal turbines. The feasibility of using CFD models to simulate time-dependent turbulent flow around a tidal turbine is then explored. Two different approaches for specifying the structure of the turbulent inflow conditions in CFD models are compared: the von Kármán spec...
متن کاملThe effect of tidal flow directionality on tidal turbine performance characteristics
With many Tidal Energy Conversion (TEC) devices at full scale prototype stage there are two distinct design groups for Horizontal Axis Tidal Turbines (HATTs). Devices with a yaw mechanism allowing the turbine to always face into the flow, and devices with blades that can rotate through 180 to harness a strongly bi-directional flow. As marine turbine technology verges on the realm of economic vi...
متن کاملEffect of Jet Shape on Flow and Torque Characteristics of Pelton Turbine Runner
In Pelton turbine, the energy carried by water is converted into kinetic energy by providing nozzle at the end of penstock. The shape of jet affects the force and torque on the bucket and runner of turbine. The nozzle of circular cross section is commonly used. In this paper attempt has been made to study the effect of four different jet shapes on the flow and torque characteristics of Pelton t...
متن کاملResearch of Flow Characteristics Hybrid Model of Steam Turbine Stage based on the Improved PSO Algorithm
Power station steam turbine stage flow characteristics show the Corresponding relationship between pressure and flow rate, which is the important research foundation for analysis of steam turbine performance and the further optimization analysis of unit. Based on strict theory analysis, this article obtained two important key characteristic coefficients such as the capacity of flow coefficient ...
