摘要：

The problem of unsteady heat transfer to pulsatile flow of a dusty fluid in a parallel plate channel has been studied. It is observed that the unsteady Part of the fluid velocity as well as of the particle phase velocity has a phase lag which increases with increase of phi, i.e. the volume fraction of the particles. The steady part or the heat transfer at the hotter plate decreases with increase of phi whereas it increases with increase of phi at the colder plate. The amplitude of the unsteady part of the heat transfer at both the plates decreases with increase of phi.
