This work has been supported by a grant from the DGICYT (Spain) under no. PB88-0140.The direct correlation function of a Huid of aligned planar hard convex orientable bodies is determined exactly using a simple form for the separation of the centers at contact. An approximate analytical proposal for the direct correlation function in terms of a reference direct correlation function of a fluid of spherical molecules is shown to lead to the exact equation of state in the high-pressure limit.engjournal articlehttp://dx.doi.org/10.1016/0378-4371(90)90264-Shttp://www.sciencedirect.com/restricted access536PhysicsMultidisciplinaryTermodinámica2213 Termodinámica
