Two-Dimensional Numerical Model of the Near-Field Flow for an Ocean Thermal Power Plant. Part 2. Simulation of the Lockheed Baseline Design
Abstract
This report describes a computation of the stratified turbulent flow- field near the Lockheed baseline Ocean Thermal Power Plant (OTPP) design, with zero ambient current. The calculation uses a two-dimensional near-field computer code NRFLO2, and approximates the flow associated with one of the four power modules by assuming a rectangular domain of depth 500 ft, which horizontal slots at one end to represent the warm inflow and the two outflows. Flow is assumed to be statistically uniform across the width of this domain. Widths of 50 ft, 100 ft, 200 ft, and 400 ft are separately assumed; the 100-ft and 200-ft computations essentially bracket the results for the prototype flow. Numerical results for the average warm inflow temperatures, in the 4 cases, are 75.7 F, 77.2 F, 77.9 F, and 78.6 F. This is with a surface temperature of 80 F. The warm outflow is defined to be 3 F cooler; the cold outflow temperature is set to 45 F. Numerical results for the OTPP-generated turbulent diffusivity indicate that it is effectively confined to the neighborhood of the plant. Its value is very small outside such a neighborhood.
