Abstract: A data storage system includes a chassis housing multiple data storage devices, such as hard disk drives, a compartment housing cooling fans, and an air plenum positioned between the fans and the storage devices. A multibody chambered acoustic attenuator, which may be installed in the air plenum, includes a plate part having airflow holes therethrough and may include a convex arched part having airflow holes therethrough and coupled with the plate part to form a chamber. Acoustic damping material lines an interior surface of the plate part and the interior and exterior surfaces of the arched part, and the airflow holes of the plate part and of the arched part are not aligned, such that direct acoustic emissions and reflections would contact the acoustic damping material and a circuitous airflow path is provided from the cooling fans to the storage devices, to reduce the acoustic sound pressure upon the devices.

Abstract: A data storage system may include multiple data storage devices, such as solid-state drives, an enclosure housing the devices, and a thermal bridge positioned in a gap between and in contact with each of the enclosure and a device, where the enclosure is cooler than the device. Thus, heat is conducted away from a hot spot of the device and to the enclosure. The thermal bridge may be flexible enough to bridge different sized gaps, while stiff enough to generate contact forces applied to the enclosure and the device. For example, the thermal bridge may be constructed primarily of copper and configured to function like a compression spring.

Abstract: Systems and methods axe disclosed herein that generally involve a double pinch criterion for optimization of regenerative Rankine cycles. In some embodiments, operating variables such as bleed extraction pressure and bleed flow rate are selected such that a double pinch is obtained in a feedwater heater, thereby improving the efficiency of the Rankine cycle. In particular, a first pinch point is obtained at the onset of condensation of the bleed and a second pinch point is obtained at the exit of the bleed from the feedwater heater. The minimal approach temperature at the first pinch point can be approximately equal to the minimal approach temperature at the second pinch point. Systems that employ regenerative Rankine cycles, methods of operating such systems, and methods of optimizing the operation of such systems are disclosed herein in connection with the double pinch criterion.

Abstract: Combustion system. The system includes a combustor generating a combustion gas and a splitter for receiving the combustion gas and dividing the combustion gas into first and second gas streams. A temperature controller receives the first gas stream, mixes it with recycled gas and introduces it into a heat recovery steam generator at a desired temperature. A mixer receives the second gas stream, mixes it with recycled gas and introduces it into the heat recovery steam generator. The cool gas that exits the heat recovery steam generator forms the recycled gas. A suitable combustor is an oxy-coal combustor.
