The silo wall pressure using the M-C criterion is then overestimated leading to a conservative silo design [34-38].

As the first step in the verification process, the excitation forces were calculated from the wall pressure fluctuations extracted by CFD calculations.
The Bernoulli principle holds that the sum of the kinetic energy (1/2 Dv2), pressure (lateral wall pressure) energy (P), and potential energy (Dgh) at any point in the system equals the sum of those three forms of energy at any other location in the system.
As indicated in Figure 6, one wall pressure transducer (P1) to explore the fluid-structure interaction as well as the wave reflection characteristics with different targets is placed about 5 mm vertically distant from the center of the bottom hull.
As Figures 6, 7, and 9 show, the flame is brighter and the combustion zone is wider; the wall pressure is higher when applying strut, which can indicate that the combustion as well as heat release of kerosene is more adequate.
[14] It has been shown that a continuous lateral wall pressure above 30 cm[H.sub.2]O compromises blood flow, and that blood flow is completely obstructed at pressures of 50 cm[H.sub.2]O and above.
Typical products for these industries are heaters, heat exchangers, reactors, and hydrocrackers, usually build as heavy wall pressure vessels (up to 350mm wall thickness).
"The FlatProp EQP product was developed in response to the changing market demand for lower inlet operating pressures of 2.0 bar (30 psig) or "wall pressure' available in hospitals and clinics," explained Rob Howard, sales and marketing director at FAS.
The model, run on a computer, can produce accurate flow fields in minutes and could allow engineers to test various shapes of chutes and troughs to find a geometry that maximizes flow, or mitigates potentially dangerous wall pressure, before ever actually designing or building equipment to process granular materials, he said.
