This study concerns development of criteria to achieve gravity independent flow condensation. Criteria developed by comparing data for horizontal flow, upflow and downflow. Two criteria developed, one to negate gravity effects parallel to and second perpendicular to flow direction. Use of separated flow model provides high accuracy in determining the two criteria.
