    摘要： In one embodiment, a calculation method of moisture loss in a steam turbine calculates first a wetness fraction at the inlet and outlet of each of stationary blade cascades and rotor blade cascades. Subsequently, the moisture loss is classified into (1) supersaturation loss, (2) condensation loss, (3) acceleration loss, (4) braking loss, (5) capture loss and (6) pumping loss, and a loss for calculation of the moisture loss is selected from the above losses (1) to (6) according to the wetness fraction of steam at the inlet and outlet of each blade cascade. An amount of each selected loss is calculated, and an amount of moisture loss at each blade cascade is calculated.

    摘要： A turbine blade cascade structure includes a plurality of blades arranged in series in a circumferential direction on a wall surface, in which a corner portion defined by the wall surface and a front edge portion of each of blade bodies supported by the wall surface, to which a working fluid flows, includes a cover portion (fillet) that extends toward an upstream side of a flow of the working fluid. The turbine blade cascade structure is capable of reducing the secondary flow loss of the secondary flow in spite of the fluctuation of an incident angle of the working fluid flowing to the front edge portion of the blade body.

    摘要： This invention provides an optimum value search apparatus, method, recording medium, and computer program product used in designing, analyzing, or testing a device having a plurality of factors that have effects on a characteristic. In this method, an orthogonal array is generated by setting level values obtained from the initial values of the factors to the coordinates of a two-dimensional table including a matrix of the characteristics and the factors. From the characteristics on the orthogonal array, characteristic values obtained on the basis of combinations of the level values of the factors of a single characteristic are grasped. A combination having a most excellent characteristic value is selected. The level values of the factors in the characteristic corresponding to the selected combination are reset in the orthogonal array. After resetting, processes are repeatedly executed to search for an optimum value as a most excellent one of the characteristic values.

    摘要： According to the present invention, incineration ashes of sewerage sludge are compacted with pressure, but without additives, to have the bulk specific gravity of 0.9-2.5. Since the green compact has sufficient strength and reduced volume in comparison with the incineration ashes before compacting, it enables mass dumping without causing secondary pollution. Moreover, if the green compact is fired to have the bulk specific gravity of 1.4-3.5, both the volume and weight are reduced much more, realizing easy handling of the resulted burned product.

    摘要翻译： 根据本发明，污水污泥的焚化灰被压力压实，但没有添加剂，使堆积比重为0.9-2.5。 由于与压实前的焚化灰相比，生坯具有足够的强度和体积减小，因此能够大量倾倒而不会引起二次污染。 此外，如果烧结坯料具有1.4-3.5的体积比重，则体积和重量都会减少得多，从而实现对所烧制产品的容易处理。
