BMPC completed thermal-hydraulic testing of a shell-and-tube heat exchanger with low-finned tubes for transferring heat from supercritical carbon dioxide (S-CO2) on the shell side to water on the tube side. The measured performance of the shell-and-t

Low-finned tubes can be effective in baffled flow heat exchangers, if the heat transfer coefficients on either side of the heat exchanger differ greatly and therefore limit the thermal conductance of the heat exchanger. Low-finned tubes can increase

Spectral control is an important consideration in achieving high conversion efficiency with thermophotovoltaic (TPV) energy conversion systems. TPV modules using front surface filters as the primary spectral control device have demonstrated conversio

Front surface spectral control filters significantly improve the efficiency of thermophotovoltaic (TPV) converters. Tandem filter designs for 0.52 and 0.60 eV cells were fabricated. Energy and angle weighted spectral efficiencies of ∼83% for the 0.

The efficiency of thermophotovoltaic (TPV) energy conversion is dependent on efficient spectral control. An edge pass filter (short pass) in series with a highly doped, epitaxially grown layer has achieved the highest performance of TPV spectral cont

Spectral control is a key technology for thermophotovoltaic (TPV) direct energy conversion systems because only a fraction (typically less than 25%) of the incident thermal radiation has energy exceeding the diode bandgap energy, E{sub g}, and can th

X-ray double crystal diffractometry (XRDCD) was used to assess cyclic microstructural deformation in a face centered cubic (fcc) steel (AISI304) and a body centered cubic (bcc) steel (SA508 class 2). The first objective of the investigation was to de
