Obtained results allow evaluating the influence of particular parts on the flow field inside cooling tower. The effect of rain zone, fill zone and flue gas injection are studied. It is shown that the flow field above the fill zone is mainly influenced by minor losses in cooling tower fill and by the controlling of the flow direction in this zone. This effect is leading to practically uniform velocity field just above the fill zone even though the flow field in the rain zone is multidimensional. The impact of flue gas injection is studied by using momentum and kinetic energy flux coefficients. The system of Euler equations for quasi-one-dimensional flow is generalized using momentum and kinetic energy flux coefficients. It is shown that the flow field inside cooling tower excluding rain zone can be considered as quasi-one-dimensional in the case where the flue gas injection is not taken into account. The effect of flue gas injection slightly deviates the character of the flow, which is still very close to quasi-one-dimensional flow in the whole domain excluding rain zone.
