These are usually solicited by the journal and if you wish to submit a Book Review or Obituary then we recommend that you contact the Editors for guidance prior to submission. We additionally publish Book Reviews and Obituaries. The processing times for Notes and Comments are the same as for Research Articles. A limited amount of supplementary online material may be included. Articles in Notes and Comments are limited to 10 journal pages and must include no more than five figures. Alternatively, the article in this category might be a comment on a published Research Letter, Research Article, or Note with a possible subsequent reply. Notes might include reports on incomplete research or revisits of earlier published work. Notes and Comments category comprises short articles and comments on specific topics with no requirement for rapid publication. Authors submitting Research Letters must include a note to the Editors justifying the need for rapid publication in view of the above criteria. If any of the special criteria are not met, the submitted article may be considered for publication as a Research Article or Note. Revised manuscripts must be returned within one month. Time from initial submission to online publication is typically three to six months, with initial reviews obtained within one month. Letters are limited in size to five journal pages, can include no more than three figures, and must not include supplementary electronic material. They are designed to present (i) new findings of timely and compelling interest to the boundary-layer meteorological research community (ii) notable early results from experimental, observational, model, and theoretical studies that are specifically suitable for brief communication (iii) preliminary research findings likely to be highly valuable to the scientific community (iv) significant extensions of earlier work. Research Letters comprise short articles requiring rapid dissemination. Time from initial submission to online publication is typically six to 12 months, with initial reviews obtained within two to three months. An article may be accompanied by a limited amount of supplementary online material when necessary, as rigorously prepared and edited as is the main article. Articles in this category are generally no more than 30 journal pages long, with a maximum of 15 figures. Research Articles are scientific articles that present results from substantial research studies or critical reviews of ongoing research. Please use this guidance to select the most appropriate category for your submission. Due to what I just said, there is no exact answer for turbulent flow, however, computer models can be used to provide a prediction on what can be expected.Boundary-Layer Meteorology publishes several types of articles, which are detailed below. The best way to think of the flow when it is turbulent is as a bunch of intertwined eddies of different sizes and different velocities. The turbulent boundary layer however, is much more difficult to predict due to its randomness. So far all that has been discussed is the laminar part of the boundary layer, since it can easily be represented through equations. Μ = Dynamic Viscosity Turbulent Boundary Layer To calculate the boundary layer’s thickness the following equation and table would be used. The reason why you may want to know the thickness of the boundary layer is because outside of the boundary layer the fluid particles will not be effected by viscous forces. Boundary Layer Thicknessįor the laminar part of the boundary layer it is possible to calculate the boundary layer thickness using the Blasius Equations. Also, the larger the Reynolds number the thinner the boundary layer becomes. As Reynolds number becomes larger the viscous effects aren’t as important at the front of the boundary layer, but become much more important as you near the end of the boundary layer. In addition to determining if the flow is laminar or turbulent Reynolds number also determines the importance of the viscous effects. To calculate the Reynolds number for fluid flow over a flat plate the following equation would be used. Depending upon the surface roughness, the transition from laminar flow to turbulent flow occurs at a Reynolds number of 2X10 5 to 3X10 6. To determine if the fluid has a laminar or turbulent flow as it moves over the object Reynolds number would be used. Depending on the length of the object and the speed of the fluid, the boundary layer could exhibit both laminar and turbulent flow. The boundary layer is due to the shear stress caused by the viscous effects of the fluid as it moves over the object. As fluid flows over a submerged object a boundary layer is formed.
