Ocean thermal energy conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of can operate with a very high capacity factor and so can operate in base load mode.. The denser cold water masses, formed by ocean surface water interaction . Analysis of the two-phase flow in a de laval spray nozzle and exit plume. and stability of the mist-lift process for open-cycle OTEC. the effects of design parameters on performance. A system model of open Rankine cycle ocean thermal energy conversion (OC-QTEC) was used to examine the effects of component performance and design on plant cost. Three components are examined in detail: an optional seawater deaeration subsystem, the flash evaporator, and a two-stage direc.t­ contact condenser.   Ocean thermal energy conversion 1.

Other articles where Open-cycle OTEC system is discussed: ocean thermal energy conversion: centred their attention on an open-cycle OTEC system that employs water vapour as the working fluid and dispenses with the use of a refrigerant. In this kind of system, warm surface seawater is partially vaporized as it is injected into a near vacuum. the feasibility of an Open-Cycle Ocean Thermal Energy Conversion (OTEC) concept. The objective of the project is to assess the economic and technological viability of the conceptual design of an Open- Cycle OTEC power plant. FSEC and Creare R&D Inc.. Hanover, New Hampshire, br~ng together complemen-.   Practical limitations mean that the largest open cycle turbine that can be built today is around MW, much smaller than for a closed cycle system. One of the major advantages of the open cycle system is that the water condensed from the turbine exhaust is fresh, not salt water, and so the plant can also serve as a source of drinking water as. The efficiency of Rankine cycle and its derivative cycles are severely affected by droplets condensed in the process of vapor expansion, which not only limit its maximum efficiency, but also cause extremely low efficiency around 3% when using low grade heat source. This paper introduces a new theory of Thermodynamic and Gravitational Cycle to explain the concept of Author: Zhang Quan.

Other articles where Closed-cycle OTEC system is discussed: ocean thermal energy conversion: His idea called for a closed-cycle system, a design that has been adapted for most present-day OTEC pilot plants. Such a system employs a secondary working fluid (a refrigerant) such as ammonia. Heat transferred from the warm surface ocean water causes the working fluid to .
