In a heated pipe, free convection is caused by the buoyancy forces of laminar flow. However, it was shown in a previous paper that free convection in a steady flow occurs when the temperature differences between air in a room and water in an unheated pipe are large. Under such experimental conditions in the case of pulsating flow, cross-sectional distributions of axial velocities are measured for water over a frequency range of 0.313 Hz to 2.1 Hz by means of a hot-wire anemometer in the present investigation. The cross-sectional distributions of instantaneous axial velocities are not the same as the Poiseullian velocity distribution. Furthermore, both the magnitude and the phase angle distributions of oscillating axial velocities are also presented.
