SOLAR ENERGY 315 diluted form, at a rate of about 220 W/m2 (see Figure 3-1). In other words, if one square meter were available for conversion of solar energy to electricity (at efficiency), the energy produced would be sufficient for just two or three light bulbs. The challenge of solar energy utilization is to concentrate it.

Fluid energy mills may be classified in terms of the mill action. In a fluidized bed jet mill, schematically illustrated in Figure 2.19, the grinding energy is created by gas streams from horizontal grinding air nozzles.Particles in the fluidized bed created by the gas streams are accelerated towards the center mill chamber colliding with slower moving particles.

Fluid energy or jet mill consists of a hollow toroid. A fluid, usually air, is injected as a high-pressure jet through nozzles at the bottom of the loop. High velocity of air creates zones of turbulence into which solid particles are fed. The high kinetic energy causes particles to collide with momentum for fracture to occur.

pumps. Energy is imparted to the liquid by means of a disk with curved vanes rotating on a shaft called the impeller. The impeller imparts kinetic energy to the fluid by means of its shape and high rotational velocity. This energy is transformed to pressure energy when the fluid reaches the pump casing (see Figure 1-12). The pressure head ...

Fluid energy milling of ibuprofen was investigated and found generally hard to mill in its dry state due to its ductility and low melting point . In the study, ibuprofen crystals of different sizes (<40 μm or 50–250 μm) and morphologies (plate-like and needle-like crystals) were first produced by controlled crystallization.
