Abstract: A turbofan engine includes a fan, a core turbine engine having one or more turbines and an exhaust section, and a hydrogen-exhaust gas heat exchanger in flow communication with the exhaust section and hydrogen flowing along a hydrogen supply line. The hydrogen-exhaust gas heat exchanger defines a load capacity factor determined by raising a product to a one-quarter power, the product being determined by multiplying a heat transfer surface area density associated with the hydrogen-exhaust gas heat exchanger by a process conductance parameter that relates characteristics of hydrogen, ambient air, and exhaust gas at takeoff, as well as a fan diameter of the fan and a number of turbine stages of the turbofan engine. The load capacity factor is between 4.37 and 28.65 for the fan diameter being between 0.5 and 3.5 meters and the heat transfer surface area density being between 500 m2/m3 and 10,000 m2/m3.

Abstract: Techniques manage an access load of a storage system. For storage devices in the storage system, access histories of the storage devices in a previous time period are received respectively. Access loads of the storage devices in a future time period are determined respectively based on the access histories of the storage devices, the future time period being between a current time point and a future time point for performing future load balancing. An access balance degree of the storage system at the future time point is acquired based on the access loads. Load balancing is performed among the storage devices in response to determining that the access balance degree satisfies a first predetermined condition. Accordingly, it is possible to determine an access load of each storage device in a storage system more accurately and ensure that the access loads of the storage devices are in a balanced state.
