The subject of the case is a PSA spray exp= osed to cross-flowing air. A small low-PSA was used f= or the study. This atomiser was developed for spraying aviation fuel Jet A-1 (kerosene) into the combustion chamber of a small gas turbine (GT) engine. The here documented operation conditions of the atomis= er and the flow velocity corresponding to the engine's low-power or steady-fli= ght conditions. The airflow is forced perpendicularl= y to the main spraying axis, which is considered a cross-flow case. The flow is homogeneous, isothermal and with low turbulence intensity, Tu.<o:p></o:p>
Similar atomisers of this type and size us= ed together with the operating pressure and cross-flow air velocity conditions= cover many industrial spray applications ranging from small GT combustors to chem= ical spray reactors. The conditions are also relevant for agriculture and domest= ic sprayers.<o:p></o:p>
The processed results of the present case = were published in [2][2]Figure 2, left:<o:p></o:p>

From a thermodynamic point of view, the ca= se is isothermal and isobaric, except for possible evaporation which can modify the droplet size [3]. Th= at can introduce thermal effects, such as the exchange of heat between the dischar= ged liquid and the surrounding air, which are otherwise unimportant. For the purpose of numerical simulations, the case features a two-way to four-way coupling between the gas and liquid phases depending on the position in the spray [4].<o:= p></o:p>
