I suggest you to try FMG initilization. Flow convergence can be accelerated if a better initial solution is used at the start of the calculation. The Full Multigrid initialization (FMG initialization) can provide this initial and approximate solution at a minimum cost to the overall computational expense. other you can try using real gas property table (RGP). 

You can refer to fluent user’s guide for more on FMG initilization: 33.10. Full Multigrid (FMG) Initialization (
