VARGAS, M. et al. A centrifuge for studies of fluid dynamics phenomena in a rotating frame of reference. Rev. mex. fis. [online]. 2002, vol.48, n.3, pp.255-266. ISSN 0035-001X.

A centrifuge for the study of fluid mechanics phenomena in a rotating frame has been constructed at the Center for Energy Research at the National University of Mexico (UNAM). The centrifuge has a 1.5 m long arm and is designed to rotate at a maximum rate of 86 rpm which corresponds to a maximum centrifugal acceleration of 13 g. This paper describes the mechanical characteristics of the centrifuge and its instrumentation. The potential of the system for performing fluid mechanics experiments in a rotating frame of reference is also discussed and sample results of natural convection in a cavity are presented.
