A non-simple heat conducting microfluid

Liu's (1973) analysis of a nonsimple heat-conducting microfluid is extended by allowing an internal polar field characterizing rigid rotations to be present in the microfluid. The existence of this field could imply the presence of rigid microinclusions, in the body which create poles by rotation while moving with the fluid. It is found that for vanishing temperature gradients, no time-dependent microrotational fields exist in the medium.
