Abstract: The liquid solid fluidized beds have been usually used in catalytic cracking, ion exchange, crystallization, and particle classification. Fluidized bed column has investigated experimentally and numerically. A numerical investigation has been done by using computational fluid dynamic software ANSYS Fluent 15.0. In this study, a spherical stainless steel has used as solid particle fluidized continuously by water. Three different values of water flow rate (10, 15, 20 l/min) have used with three different values of static head of the solid particles (2, 2.5, 3 cm). The pressure of the fluidized bed has been measured at four different location of the test section 20 cm apart and the flow behavior at the test section has monitored by using AOS high speed camera. The experimental data has compared with numerical solution and a good agreement has been found. It can be observed that the expansion of the solid particles and the pressure inside the bed increased as the water flow rate and static bed height increased.

Abstract: This study is concerned mainly with high noise produced by automated olive mills and its negative impact on human health. This study looks at what caused this problem such as the application of building codes concerning user exposure to noise and protective measures for workers. Long working period exposure to high noise, particularly mill workers, causes health and ear illness. Noise levels are measured in several olive mills in Jordan, recorded data was analyzed and findings indicated that noise level is higher than the maximum noise limits allowed by the Jordanian code. This study concludes design solutions and legislative procedures to improve noise control in olive mills.
