Example: Heating of a fluid food product in an indirect contact heat exchanger with the fluid food flowing in the inside tube and hot water flowing through the outside tube. Fluid streams close to the center of the pipe flow the fastest and also heat up the slowest due to their distance from hot water. Thus, they receive minimal heat treatment.

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.

Fluid energy mill: Principle-It works on the principle of impact and attrition. It consists of a loop of a pipe, which has a diameter of 20 to 200 mm, depending on the overall height of the loop which may be up to about 2 meters, a fluid, usually air, is injected at high pressure through nozzles at the bottom of the loop, giving rise to a
Governing Equations of Fluid Flow and Heat Transfer Following fundamental laws can be used to derive governing differential equations that are solved in a Computational Fluid Dynamics (CFD) study [1] conservation of mass conservation of linear momentum (Newton's second law) conservation of energy (First law of thermodynamics)

This con-sumption represents 15 percent of the electricity used by motors.3 Similarly, in the commercial sector, electricity needed to operate fan motors composes a large portion of the energy costs for space conditioning. Performance may range from "free air" to several pounds per square inch gage (psig ...
A high-energy mill was designed and built with the purpose of processing magnesium (Mg) powders. The main characteristics of the mill are grinding capacity of 1 kg and demolition elements of 10 kg; it has a distributed form to the interior ten blades of similar geometry, six of which are of the same size and four of them were increased in length in order …

The fluid entering or leaving a control volume possess an additional energy, the flow work (Pv). Hence, the total energy of a flowing fluid becomes. θ = Pv + u + v 2 /2 + gz. where θ = methalpy, the total energy of a flowing fluid . The definition of enthalpy gives. h = Pv + u. Replacing Pv + u by h yields. θ = h + v 2 /2 + gz
industry and building energy consumption today. Industry: boilers are used for power generation, process heat (e.g., refineries, petrochemicals, paper mills, tire manufacturing, etc.) and heating. In buildings, boilers are used for steam primary heat, terminal reheat systems, water heating and absorption chillers.

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.
