船舶通風の流体力学的研究 (第2報)

抄録

In the first report, observation was made on the two dimensional flow, where it was proved that stream lines and stream velocities are identical with the result of hydrodynamical calculation. In this 2nd report, the author intends to proceed into three dimensional flow. This time, however, experimental method was mainly substituted for hydrodynamical calculation, since the calculation is hardly possible in the field of three dimensional flow. To begin with, some fundamental experiments were made to clarify the scale effect among model experiments in water current, that in air current and the facts in actual ships. The result finally reached is that efficiency of ventilation in actual ship can be measured by performing model experiments in water current.
