ジャーナル フリーA series of wind tunnel tests was conducted on the fluttering and scattering behavior of “hikkake-san-gaware”, a hook type rooftiles, which arc used widely for roofings of Japanese wooden dwellings . 1/20 scale models of two-storied dwellings of a rectangular plan and 1/20 miniature rooftile models made by brass cast were used for the test . The boundary layer was realized in the wind tunnel corresponded to that on rural districts,
Following results were obtained:
(1) The spatial distribution of rooftile scattering was non-symmetric, Rooffiles on the right side roofs were susceptible to scattering .
(2) Locations of fastening in the customary tile-roofing works was effective to prevent roof tile scattering in strong winds of loss than about 40m/s .
(3) Based on the consideration on the wind resistant mechanism iu hikkake-sangawara roofing system, the value of wind force coefficient for the first fluttering of rooltiles was obtained .抄録全体を表示PDF形式でダウンロード (3443K) -

ジャーナル フリーCharacteristics of wind forces on airport control towers with typical plans and with C without the office buildings were investigated by a wind tunnel .
The results obtained are discussed from the view point of securing of serviceability of the tower in strong winds. Main results are as follows,
(1) In the case of without the office building, towers consisted of three legs of triangular cross-section are advantageous.
(2) In the case of with the office building wind force behaviors were comparatively improved for all towers.抄録全体を表示PDF形式でダウンロード (909K) -

ジャーナル フリーA new flow-visualization system by using infrared thermography has been proposed. The system was applied to theflow around a two-dimensional circular cylinder with smooth surface, and its validity was examined. The relation between the surface temperature distribution on the cylinder and the flow characteristics was clarified.
By comparing the present results with the previous ones given by the other investigators The validity of the system was recognized. Furthermore, the variation of the surf ace temperature distribution on the cylinder with the Reynolds number in the subcritical and critical Reynolds-number ranges was examined in detail, The results indicated that the flow pattern changed suddenly at Re≅ 3.3× 105.抄録全体を表示PDF形式でダウンロード (2155K) -
