@@angchitinh5155 A starting point design for grooving is given on the Air Lubrication Calculator, by (Steven) AbbottApp. It is based on the heuristic given in my 1996 Mechanics of Rollers book which has been vetted by Dr Ron Swanson of 3M and others. Cross hatching is best for thin films (to avoid wrinkling), no matter the width, depth and pitch of the grooving required for air handling.
