FLOW CHARACTERISTICS OF OPEN CHANNELS BASED ON PATCH DISTRIBUTION OF PARTIALLY DISCONTINUOUS RIGID COMBINED VEGETATION

Flow characteristics of open channels based on patch distribution of partially discontinuous rigid combined vegetation

To clarify the flow characteristics Leather of open channels under the combined distribution of vegetation in a patch, this study used the computational fluid dynamics tool FLUENT and the Reynolds stress model to design four combined and four discrete distribution modes under two different inundation states (submerged and non-submerged).The flow ch

Wideband strip antenna surrounding a ground plate

Abstract A wideband planar antenna, which is composed of a ground plate and a strip surrounding the plate, is proposed.Wideband impedance matching with fractional bandwidth over 130% is achieved by making the distance between the strip and the ground plate stepwise so that the distance becomes wider in the tip side.The electric field in the slot li

Rehabilitation of Mature Gas Fields in Romania: Success Through Integration of Management Processes and New Technology

Nature oil and gas fields are difficult to rehabilitate effectively because of the economics of declining production.Many fields are abandoned prematurely when their life could be prolonged significantly through application of new technology.Romgaz (a national exploration and production company) and Schlumberger (an integrated oilfield services Tan
