The advisability of using combustion chambers with a toroidal recirculation-mixing zone in small-sized gas turbine engines

MATEC Web of Conferences, 2018
The interrelations between the size of the gas turbine engine (GTE) and the size and workflow of the combustion chamber (CC) were considered. On the base of analysis of workflow organization the design of CC with toroidal recirculation mixing zone was ...

Mathematical model of bent-flattened sintered-grooved heat pipe with concept of receding-and-excessing fluid

Case Studies in Thermal Engineering, 2021
A mathematical model that uses the concept of evaporation and condensation to explain the process of heat and mass transfer within the bent, flattened heat pipe has been established to predict its wall temperature and thermal resistance.
