    Abstract
    We investigate the flow past circular, square, and triangular cylinders embedded on spherical and cylindrical surfaces and quantify the effect of the embedding surface curvature on the flow characteristics. For the circular cylinder, we examine three Reynolds numbers Re=40,100, and 1000 based on cylinder diameter (D), and vary the normalized embedding surface curvature values κD, where κ is the maximum principal curvature, from 0 (flat surface) to 1/12. Measures of fluid dynamical quantities of interest: drag coefficient Cd, lift coefficient Cl, Strouhal number St, pressure coefficient (Cp), friction coefficient (Cf), vorticity magnitude (ω∗), street speed Vst, street wavelength λ, length of stationary vortex pair (L), and separation angle (θsep) show an insignificant effect of the surface curvature. For the range of embedding surface curvature values, the dynamics of the flow past a stationary circular cylinder exhibits near universality, and is essentially independent of the embedding surface curvature. Our conclusion is further consolidated by the similar insensitivity to the embedding surface curvature exhibited by flows past a stationary cylinder having a square or triangular cross-section.

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. For anonymous users the allowed maximum amount is 50 search results.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
