- The papers deal with the optimization of the evaporator of a nonconventional combustion engine. Lithium bromide liquid (LiBr - an alternative cooling medium) flows in a cooling circuit of a nonconventional energetic unit. The solved energetic system is defined in the area of trigeneration systems. The mentioned system is a source of electric energy, cold and heat too. The space geometrical model corresponding to the geometry of the original evaporator is created in the CAD (Computer Aided Design) software CATIA. Only one half of the evaporator is created because of the decrease in the demand on the computational means. This CAD model is then imported into the preprocessor Gambit. The imported model is repaired and a suitable mesh is then created. The last step is the definition of the types of boundary conditions. The completed computational mesh is then exported from Gambit and imported into the CFD (Computational Fluid Dynamics) software Fluent. Fluent is used for the numerical simulation of the cooling medium flow in an evaporator. The simulation shows the filling of the evaporator cone, the time when the cooling medium starts to pour through the edge of the evaporator cone, the filling of the evaporator ring and finally also the fact that the off-take is able to take away the needed amount of cooling liquid from the evaporator.
