BartoszZajaczkowski,PhD
Introduction:
I am a researcher and a lecturer at the Faculty of Mechanical and Power Engineering at Wroclaw
UniversityofScienceandTechnology(WrUST).Inmarch2009IreceivedmyPhDdegreewithhonours
bydefendingathesisonheatandmasstransferprocessesinadsorptionsystems.Thisgavemethe
opportunitytoworkasapost-doctoralresearchfellowintheUnitedStatesandintheNetherlands.
Currently,IamemployedasanAssistantProfessorintheDepartmentofThermodynamics,Theoryof
MachinesandThermalSystemsattheFacultyofMechanicalandPowerEngineering.
My research interests include thermal and mechanical processes, particularly in the area of power
engineering, environmental engineering and cooling. Currently I focus on three specific research
topics:modernrefrigerationtechnologiesforintegratedco-generationandtri-generationsystems(i.e.
adsorption refrigeration), low-pressure phase transitions, and implementation of nanoparticles in
ordertoincreasephysicalandthermalcapabilitiesofrefrigerants.Ispecializeintheoreticalanalyses
based on numerical simulations of complex systems (simulations based on lumped parameter
differentialmodelsdescribedwithmultiplebalanceequations).
FormanyyearsIhavebeenanactivememberofvariousnon-profitorganizationsforstudentsand
