A continuum model, based on rigorous mass and energy balance equations developed from Nagaiah et al., is used for the three-dimensional simulations. The three-dimensional model equation for nozzle spray is reformulated in comparison to Heinrich. For solving the non-linear partial differential equations with boundary conditions a finite element method is used for space discretization and an implicit Euler method is used for time discretization. The time-dependent behavior of the air humidity, air temperature, degree of wetting, liquid film temperature and particle temperature is presented using two different sets of experimental data. The presented numerical results are validated with the experimental results. Finally, the parallel numerical results are presented using the domain decomposition methods.en0098-135420081228772890Backward Euler methodConvection-diffusion-reaction equationsFinite element methodFluidized bedsGranulationHeat and mass transferLiquid injectionParallelizationJournal Article10.1016/j.compchemeng.2008.02.009Journal Article
