  Using an analytical model and numerical simulations, we show that acoustic
waves generated by turbulent motion in intracluster medium effectively heat the
central region of a so-called ``cooling flow'' cluster. We assume that the
turbulence is generated by substructure motion in a cluster or cluster mergers.
Our analytical model can reproduce observed density and temperature profiles of
a few clusters. We also show that waves can transfer more energy from the outer
region of a cluster than thermal conduction alone. Numerical simulations
generally support the results of the analytical study.
