Open‐cycle OTEC systems with freshwater product: Effects of noncondensable gases on performance of condenser

An open‐cycle ocean thermal energy conversion (OC‐OTEC) system is one of the energy conversion methods used to generate electricity from ocean thermal energy. For the OC‐OTEC system, steam evaporated from the surface seawater due to flash evaporation drives the turbine. At that time, dissolved gas such as air is introduced into the low‐pressure system (OC‐OTEC system) as the noncondensable gas, which degrades the performance of condensation heat transfer. In this paper, a small‐scale OC‐OTEC experimental unit experimentally investigates the effect of noncondensable gas on the heat transfer performance in a condenser. The experimental results are discussed in comparison with theoretical estimation by the Sparrow–in method. It is shown that the condensation is occupied by heat and mass transfer near a condensation surface and that the condensation efficiency is affected by exhaust quantity of noncondensable gas at a relatively high concentration ratio of condensable gas. © 2005 Wiley Periodicals, Inc.

Analysis and Optimization Laminar Viscous Flow Through a Channel

Optimizing of laminar viscous flow through a pipe by two dimensionless values is investigated analytically. Dimensionless entropy generation and pumping power to heat transfer rate ratio are used as basis for constant viscous and the temperature dependence on the viscosity. For this matter we calculate entropy generation and pumping power for a fully developed in a pipe subjected to constant wall temperature for either constant viscosity and the variable viscosity. The variation entropy generation increase along the pipe length for viscous fluid is drawn, either the variation summation dimensionless entropy generation and the pumping power to heat transfer rate ratio are varying the fluid inlet temperature for fixed pipe length and are varying pipe length for fixed fluid inlet temperature are drawn. For low heat transfer conditions the entropy generation due to viscosity friction becomes dominant and the dependence of viscosity with the temperature becomes essentially important to be considered.

An analytical model for charge pumping below strong inversion and accumulation

A compact analytical model for charge pumping (CP) is derived. It accounts for emission during the high and low gate bias levels and assumes instantaneous transition edges. This model, which does not apply on the top of the CP curves when using large gate voltage swings, where emission fully proceeds during the transitions edges of the gate signal, applies on all the other regions provided that the transition times of the gate signal are much shorter than the times at steady state biases. Therefore it holds at large bias swings on both edges of Elliot curves and at small bias swings on the whole Elliot curves provided that the interface traps are completely filled [1]. It is compared with the analytical model proposed by Wachnik and Lowney [2] in which emission is not accounted for at all. This model, which holds at Elliot curve maxima when small voltage swings are used, has been shown to be extremely useful for studying interface trap properties [1, 2, 3 and 4]. The CP model proposed primarily, that of Brugler and Jespers [5], is used as a reference. The model derived in this article very satisfactorily fits the experimental curves in the regions of large CP current where it holds. Discrepancies at low current levels are due to the well-known contribution of the transistor source and drain regions or could be due to edge effects. Comparing the different models and the experimental curves allows to evaluate emission and capture during different regions of the gate bias period. The three regions of CP response, depending on the gate voltage swing and involving or not emission and the full filling of the interface traps, are also evidenced.
