Ocean Thermal Energy Conversion (OTEC) Development of an Apparatus to Measure Biofouling Effects on Heat Exchangers in Ocean Environments. Design Report

摘要

In March 1977, Pacific Northwest Laboratory of Battelle (BNW) negotiated a contract with LMSC to design, fabricate, and proof test an apparatus that is intended for use in (1) establishing the severity of the biofouling problem and its effect on heat transfer under OTEC operating conditions, (2) measuring the effectiveness of potential countermeasures, and (3) obtaining accurate heat transfer data that will be used in the design of OTEC heat exchangers. The contract has three tasks: Task I Design of the Apparatus, Task II Fabrication and Laboratory Testing of the Apparatus, and Task III Ocean Testing of the Apparatus. This report discusses Task I--Design of the Apparatus, which is now complete. The system incorporates thermoelectric modules to provide the heat flux and thermistors for temperature monitoring. Design, calibration, and operation of the test device are described, and drawings are included. (ERA citation 03:049789)
