  • There is an ever-increasing need to understand turbulent and multiphase combus- tion due to their broad application in energy, environment, propulsion, transporta- tion, industrial safety, and nanotechnology. More engineers and scientists with skills in these areas are needed to solve many multifaceted problems. Turbulence itself is one of the most complex problems the scientific community faces. Its complexity increases with chemical reactions and even more in the presence of multiphase flows.

  • 1 Throughout this report, we use the term “WT/PT facilities” to mean wind tunnel facilities and propulsion test facilities, that is, the type of NASA facilities we assessed. Since individual facilities within this designation can be either wind tunnel facilities, propulsion test facilities, or both, “WT/PT facilities” serves as a generic term to encompass them all. That being said, when a specific facility is talked about, for clarity, we refer to it as a proper

  • The size and principal characteristics of a new ship are determined primarily by its mission or intended service. In addition to basic functional considerations, there are requirements such as stability, low resistance, high propulsive efficiency, and navigational limitations on draft or beam, all of which influence the choice of dimensions and form. Within these and other basic constraints, the ship’s structure must be designed to sustain all of the loads expected to arise in its seagoing environment.

  • The permanent-magnet synchronous machine (PMSM) drive has emerged as a top competitor for a full range of motion control applications [1–3]. For example, the PMSM is widely used in machine tools, robotics, actuators, and is being considered in high-power applications such as vehicular propulsion and industrial drives. It is also becoming viable for commercial/residential applications. The PMSM is known for having high efficiency, low torque ripple, superior dynamic performance, and high power density.

  • Vehicles that utilize more than one energy source for propulsion are usually termed hybrid vehicles. Although the onboard energy storage system (ESS) may be a flywheel or a hydraulic accumulator, most hybrid vehicles use chemical batteries or capacitors and are termed hybrid-electric vehicles. Fuel cells (FCs) may be used in hybrid-electric vehicles as primary power sources instead of conventional internal combustion engines (ICEs). In this article, ICE–battery hybrid transit buses are discussed specifically and contrasted with conventional drive buses. ...

  • The recent fuel cell (FC) development worldwide has always been accompanied by a number of studies and projects investigating the applications of FCs onboard ships. Almost all possible FC types and different fuels such as hydrogen, natural gas (liquefied or pressurized), liquefied pressurized gas (LPG), methanol, and maritime diesel have been considered. These applications of FCs are still mainly focused on onboard power generation (OPU) and propulsion.
