Problem with boussinesq!

I am trying to simulate the heat transfer from hot water to PCM ( phase change material) in a double pipe heat exchanger.(It makes PCM to melt)
I modeled the problem in 2D at inlet of exchanger where the inner tube has constant tempreture and outer tube is adiabatic.
Because of phase changing in PCM,the density is not constant and the bouyancy is important;so I should use Bossinesq as density.
But the problem is when I model density constant, it is normal, but when I use bossinesq it is extraorinary in comparison with my source.
I attached my answers and also the source paper.
Please help me as soon as possible to find out what is the problem?
