Particle-based technologies include directly irradiated designs (free-falling, obstructed, centrifugal) and enclosed designs (gravity fed, fluidized) [in Advances in central receivers for concentrating solar applications/ Clifford K Ho]... particle/fluid flows in pipes have received a lot of attention in many areas: can we think of integrating such "HTF" in central receiver technologies..
Jet pumps are widely used in many industry branches like chemical, petrochemical, energy and even in food industry. Among many advantageous of jet pumps the most important are:
no moving parts, simplicity, reliability and relatively low cost. Such features cause that jet pumps are used for transport of extremely hazardous liquids, slurries or even mixture of liquids and solid particles [1]. There is available a lot of design of jet pumps, but the main group we can distinguish is pump with circumferential or central nozzle. For the transport of solid objects the more convenient is to use jet pump from the first group. Jet pumps can also be distinguish depending on the driving and driven fluid. The jet pump in which both streams are liquids is knows as Liquid-Jet-Liquid pump. Such pumps can be used also for transport liquids which contains solid particles.
