The dataset contains the all information with which the numerical results have been obtained shown in the paper "Joukowsky actuator disc momentum theory", Wind Energy Science, preliminary DOI 10.5194/wes-2016-55. The equations are given in the paper and in the preceding paper "Potential flow solutions for energy extracting actuator discs" Wind Energ. 2016; 19:1391–1406, DOI 10.1002/we.1902. With this the flow solutions can be recalculated and reanalysed.
