Author : Saksena, M.P.;Saxena, S.C.
Source : Defence Science Journal ; Vol:16(4) ; 1966 ; pp 235-246
Subject : 536 Thermodynamics
Keywords : Thermal conductivity;Gas ;Helium
Abstract : This paper describes a method for determining the thermal conductivity of a gas by using a thermal diffusion column and uses it for finding the thermal conductivity of air and helium upto 140 degree centigrade. The study widens the scope for finding the thermal conductivity of a gas at still higher temperatures. |

Author : Acharya, H.K.
Source : Defence Science Journal ; Vol:5(1) ; 1955 ; pp 21- 34
Subject :
Keywords : World war ;Gas
Abstract : The preparation and properties of the most important war gases which were largely used in the field during World War I are briefly reviewed. Technical and tactical aspects of these gases, and methods of their detection and decontamination have been stressed. |
| | Sonic Discontinuities in a Radiative Gas
Author : Verma, B.G. ;Ojha, S.N.
Source : Defence Science Journal ; Vol:22(1) ; 1972 ; pp 31-38
Subject : 53 Applied Physics
Keywords : Gas ;Spherical waves
Abstract : The behaviour of sonic discontinuities when a perfect gas is subjected to radiation has been studied. The growth and decay of plane and spherical waves has also been studied after obtaining second third order compatibility. |
