Transparent Inflatable Column Film Dome for Nuclear Stations, Stadiums, and Cities
Figure 13
Daily heat balance through 1βm2 of dome during the coldest winter day versus Earthβs latitude (Northern hemisphere example). Data used for computations (see (6)β(14)): temperature inside the dome is = +20Β°C, outside are = β10, β30, β50Β°C; reflectivity coefficient of mirror is = 0.9; coefficient transparency of film is = 0.9; convectively coefficients are = = 30; thickness of film layers are = = 0.0001βm; thickness of air layer is Ξ΄ = 1βm; coefficient of film heat transfer is = = 0.75, for air = 0.0244; ratio of cover blackness = = 0.9; for louvers, .
