Part 7 (of 9) -- 1 July 1996 through 4 July 1996 -- Montpellier, Fr -- 46123The initial laminar thermal boundary-layer flow over an impulsively started, isothermal, rotational symmetric, vertical body spinning in a quiescent fluid is investigated. Velocity components and temperature are expanded in series in powers of time. Leading and first order functions are obtained analytically and second and third order functions are determined numerically. Application of the general results to a sphere determines the extent of the unseparated and separated boundary-layer flow regimes which are in agreement with the existing experimental observations.eninfo:eu-repo/semantics/closedAccessAcceleration; Boundary Layer Flow; Fluids; Functions; Laminar Flow; Numerical Methods; Spheres; Temperature; Velocity; Viscosity; Quiescent Fluid; Spinning Body; Unsteady Free Convection; Velocity Components; Heat ConvectionConference Object78677842-s2.0-0030415515N/A
