Semiconductor Bridge Cable Test

Description: The semiconductor bridge (SCB) is an electroexplosive device used to initiate detonators. A C cable is commonly used to connect the SCB to a firing set. A series of tests were performed to identify smaller, lighter cables for firing single and multiple SCBs. This report provides a description of these tests and their results. It was demonstrated that lower threshold voltages and faster firing times can be achieved by increasing the wire size, which reduces ohmic losses. The RF 100 appears to be… more

Testing of the Sunstove Organization`s Sunstove Solar Oven

Description: A Sunstove Organization`s Sunstove was tested at Sandia`s Solar Thermal Test Facility. It was instrumented with five type K thermocouples to determine warm-up rates when empty and when a pot containing two liters of water was placed inside. It reached inside air temperatures above 115{degrees}C (240{degrees}F). It heated two liters of water from room temperature to 80{degrees}C (175{degrees}F) in about two hours. Observations were made on the cooling and reheating rates during a cloud passage. … more

Power Performance Testing Progress in the DOE/EPRI Turbine Verification Program

Description: As part of the U.S. Department of Energy/Electric Power Research Institute (DOE-EPRI) Wind Turbine Verification Program (TVP), tests are conducted to characterize the power performance of individual wind turbines at each wind project. The testing is performed in a variety of terrain types, including mountains, plains, deserts, and coastal tundra; and under a wide range of atmospheric conditions, from arid to arctic. Initial results and experiences of the testing were reported the WindPower 2000… more

Testing of the Burns-Milwaukee`s Sun Oven

Description: A Burns-Milwaukee Sun Oven was tested at Sandia`s Solar Thermal Test Facility. It was instrumented with five type K thermocouples to determine warm-up rates when empty and when a pot containing two liters of water was placed inside. It reached inside air temperatures above 160{degrees}C (320{degrees}F). It heated two liters of water from room temperatures to 80{degrees}C, (175{degrees}F), in 75 minutes. Observations were also made on the cooling and reheating rates during a cloud passage. The a… more

Development & Testing of Industrial Scale, Coal Fired Combustion System, Phase 3

Description: In the first quarter of calendar year 1998, 4 days of tests on the 20 MMBtu/hr combustor-boiler facility were performed as part of a parallel project on sulfur capture in slag. No work was performed on the present project in this quarter. The total test days on the Philadelphia facility to the end of March 1998 was 108, of which 34 tests were part of the other DOE project. This exceeds the planned 63 test days for this project. All key project objectives have been exceeded including combustor d… more

Excitation Methods for Bridge Structures

Description: This paper summarizes the various methods that have been used to excited bridge structures during dynamic testing. The excitation methods fall into the general categories of ambient excitation methods and measured-input excitation methods. During ambient excitation the input to the bridge is not directly measured. In contrast, as the category label implies, measured-input excitations are usually applied at a single location where the force input to the structure can be monitored. Issues associa… more

Development & Testing of Industrial Scale, Coal Fired Combustion System, Phase 3

Description: In the third quarter of calendar year 1997, 10 days of tests on the 20 MMBtu/hr combustor-boiler facility were performed. The total test days on the Philadelphia facility to the end of September 1997 was 93, of which 19 tests were implemented as part of another DOE project. This exceeds the planned 63 test days for this project. Key project objectives have been exceeded, including NO emissions as low as 0.07 lb/MMBtu and SO emissions as low as 0.2 x 2 lb/MMBtu. The tests in the present quarter … more

Effect of Water Injection on Knock-Limited Performance of a V-Type 12-Cylinder Liquid-Cooled Engine

Description: Report presenting an investigation conducted to determine the effect of water injection on the knock-limited performance of a V-type 12-cylinder liquid-cooled engine. The knock-limited performance tests were made at an engine speed of 3000 rpm with carburetor-air temperatures of 158, 101, and 50 degrees Fahrenheit at water-fuel ratios of 0, 0.2, 0.4, and 0.6.

A NORMETEX MODEL 15 M3/HR WATER VAPOR PUMPING TEST

Description: Tests were performed using a Model 15 m{sup 3}/hr Normetex vacuum pump to determine if pump performance degraded after pumping a humid gas stream. An air feed stream containing 30% water vapor was introduced into the pump for 365 hours with the outlet pressure of the pump near the condensation conditions of the water. Performance of the pump was tested before and after the water vapor pumping test and indicated no loss in performance of the pump. The pump also appeared to tolerate small amounts… more

Reproducibility: A Major Source of Uncertainty in Weighing

Description: Balance confirmation tests usually include eccentricity, linearity, and repeatability. The latter is a measure of the random variability of the instrument. Further, repeatability is usually based on 10 consecutive measurements of a mass standard in a short period of time. The test results are used to verify the balance performs within manufacturer's specifications. These test results are often used in calculating an estimate of the uncertainty in measurements made with the balance. Uncertainty … more

RHIC status

Description: The design and construction status of the Relativistic Heavy Ion Collider, RHIC, which is in the seventh year of a nine year construction cycle, is discussed. Those novel performance features of a heavy ion collider that are distinct from hadron colliders in general are noted. These features are derived from the experimental requirements of operation with a variety of ion species over a wide energy range, including collisions between protons and ions, and between ions of unequal energies.
