Abstract: 
We studied connections between the parameters of the Knudsen layer and collision region of a comet’s atmosphere on the basis of the hydrodynamics simulation of the flow of gas/dust mix in the collision region. The reliability of the results derived for flows with different gas/dust relationships is estimated. The problem is important for the investigation of mechanisms realizing the gas/dust connection within the thin Knudsen layer of a comet’s nuclear. Within the framework of the model proposed we derived a relationship between the optical thickness of a dusty comet’s atmosphere and the dust production rate of a comet’s nuclear and gas parameters on the exterior boundary of the Knudsen layer.
Keywords: comet's atmosphere, dust production rate, gas/dust mix, optical depth
