The effect of the ferrofluid magnetic particle concentration on the thermal diffusivity

摘要: Thermal diffusivity results obtained with the collinear mirage technique, are reported for different concentrations surfacted ferrofluid and a set of acid ferrofluids variable pH values. The technique was used because materials semitransparent have low thermal diffusivities. show that, as magnetic particles concentration increases, also increases. Their behaviour differs from that ferronematics [1]. geometry waves propagating through material can account difference.
