Language and Style Axis-boundary conditions for the SGS stresses in case of scale similarity and mixed-type models are specified in terms of GS velocities at the axis so as to be compatible in the statistical mean with expressions for the axis values of… following from the kinematics of homogeneous axissymmetric turbulences as well as from the statistically averaged dynamic equations for the GS velocity field taking into account statistically steady and homogeneous flow conditions. Axis-boundary conditions for the SGS stresses in case of scale similarity and mixed-typemodels are specified in terms of GS velocities at the axis. This is done so that they are compatible in the statistical means…for the GS velocity field. Statistically steady and homogeneous flow conditions are also taken into account. Language and Style Expressing your ideas concisely Being concise in your writing means expressing your ideas in as few words as possible. This involves not repeating what you say, cutting out the use of unnecessary words. If your sentences are too wordy, they are difficult for the reader to understand. Wordy: We continued our activities in the development of new ________for________. Good: We have developed new ______for _________. Wordy: The different materials that contribute to an environmental impact have different potential environmental effects. Good: Different materials have different environmental impacts. In the investigation of water cresting behavior, we found that the complication of modeling water cresting analytically arises from the fact that a part of the boundary representing an interface which is defined as oil-water-interface is itself unknown. Not only is the interface no longer a simple geometrical form, but the exact shape of the interface in unknown and is therefore part of the required solution.
