A thermosensitive liquid crystal suspention method gives the temperature field on fluid in a drum rotated by a heating center shaft inserted in. The obtained temperature field indicates the heat transfer process pattern in the fluid, which is classified associating with the governing equations. When the Taylor number is larger, the forced rotation flow generated by the inertia force is dominant and the heat radially diffuses by the heat conduction (Pattern(c)). When the Grashof number is lager and/or the Peclet number is smaller, i.e. the Grashof number per the Peclet number is larger, the buoyant force acting on the heated fluid is larger and the heat convention is dominant on the heat transfer, so that heated fluid pools in the upper region inside the drum (Pattern(a)). In the case that the forced rotation effect is almost equivalent to the heat convection effect, the heated fluid rapidly prevails in the whole region inside the drum (Pattern(b)).
