Studies on the Transmission of the Infrared Radiation through Smoke Layers (2)

Abstract

The transmissivity of black body radiation through smoke layers was calculated by the formula (1).
The temperature of black body is 300°K, and the properties of smoke droplets are assumed as follows; droplets radii; 0.65μ·0.80μ·0.95μ·110μ, the ratio of droplets numbers; (0.65):(0.80):(0.95):(1.10)=3:4:6:4, complex refractive index; as in Table 4.
The efficiency factor for extinction “Qext.” are calculated at first by means of Aden's method, the result is shown in Fig. 2. Then the transmissivity are calculated and shown in Fig. 3. The calculated transmissivity was in coincidance with the experimental one.
