    • An electric component (electric-power convertor) and a pair of air-conditioning ducts are arranged side by side in a vehicle width direction. In case in which a rear end portion of the electric component is located in back of an outlet of the air-conditioning duct, the electric component is formed in a notch shape such that a duct-side edge portion thereof extends obliquely rearward and in a specified direction, in the vehicle width direction, away from the air-conditioning duct. Accordingly, it can be properly prevented that a conditioning air toward a passenger seated in a rear seat is blocked with the electric component arranged between a seat cushion of a front seat and a floor panel and receives any improper influence of heat emitted by the electric component, or the electric component receives any damage from the conditioning air.

    • A method is provided for analyzing the effects of bubbles on skin-friction reduction in a ship cruising in a bubbly flow field. A shear stress decrement &tgr;t produced by a bubble in a flow field is obtained in a high frequency band region, in which a product of a bubble time-constant T and a turbulence frequency &ohgr;L in a flow field is sufficiently greater than 1, based on a resistive force &Dgr;Rv acting on a bubble derived from the bubble movements in a fluid flow direction along a ship surface and in a direction at right angles to a ship wall surface. Assuming that the shear stress a decrement is generated by a decrease in a gas mixing length, an expression for the operative wall constant &kgr;1 for bubbly flow including a parametric bubble diameter db is derived. Based on an expression relating the operative wall constant &kgr;1 and a local friction factor Cf in bubbly flow, and an expression relating the normal wall constant &kgr; in non-bubbly flow and a local friction factor Cf0 in non-bubbly flow, an analytical solution is obtained for a skin-friction ratio Cf/Cf0.
    • 提供了一种用于分析泡沫对气泡流场中船舶巡航中的皮肤 - 摩擦减少的影响的方法。 在流场中的气泡时间常数T和湍流频率ωL的乘积充分大于1的高频带区域中获得由流场中的气泡产生的剪切应力减小和t, 基于作用在沿着船舶表面的流体流动方向的气泡运动产生的气泡和与船舶壁表面成直角的方向上的阻力DFTARv。 假设剪切应力由于气体混合长度的减小而产生减量,则推导出包括参数气泡直径db在内的用于气泡流的操作壁常数kappa1的表达式。 基于与气泡流中的操作壁常数kappa1和局部摩擦系数Cf相关的表达式,以及与非气泡流中的正常壁常数kappa和非气泡流中的局部摩擦系数Cf0相关联的表达式,解析解是 获得的皮肤摩擦比Cf / Cf0。
