Minimization of residual stresses for rolled long products
 Kubík, Petr ; Raudenský, Miroslav (referee) ; Petruška, Jindřich (advisor)
This thesis deals with simulation of cooling of rail during its passing through cooling device which has been designed by the heat transfer and fluid flow laboratory. Inputs of the computational model have been set up to get best possible correspondence between outputs of the computational model and results of experimental measurement. The solution with using of model of austenitic stainless steel is provided in first part of the thesis. The solution with considering model of carbon steel is performed in next part. Using of model of carbon steel allows including evolution of latent heat during phase changing. A fields of residual stress has been calculated for different cooling conditions in the last part of this thesis.

Design of a heat pump for a cooling system of controlled wine fermentation
 Brucháček, Rudolf ; Hejčík, Jiří (referee) ; Toman, Filip (advisor)
This bachelor’s thesis deals in the first part with research on the issues of heat pumps and the use of cooling devices for controlled fermentation of wine. The second part involves the design of a specific heat pump for this cooling device. It is an air-to-water heat pump with the possibility of reversible operation. The design of the device components is realized using calculation software from well-known companies specializing in this field (Select 8, SSP G8, Coolsector 2, Coolpack). The output of the thesis is a specific component design and an energy evaluation using the coefficient of performance.
