Experimental Investigations On The Momentum Pressure Drop During Flow Boiling Of R134a
Muszynski, Tomasz; Andrzejczyk, Rafal; Dorao, Carlos Alberto (Journal article; Peer reviewed, 2018)The article presents experimental investigations of the pressure drop during two-phase flow. Experiments were performed for both adiabatic and heated flow of R134a. Obtained flow patterns were compared with the literature. ... -
Experimental validation of pressure drop models during flow boiling of R134a – effect of flow acceleration and entrainment
Muszynski, Tomasz; Andrzejczyk, Rafal; Dorao, Carlos Alberto (Journal article; Peer reviewed, 2018)A crucial step to assure proficient work of power and process apparatus is their proper design. A wide array of those devices operates within boiling or condensation of the working fluid to benefit from high heat transfer ... -
Heat transfer and pressure drop characteristics of the silicone-based plate heat exchanger
Muszynski, Tomasz; Andrzejczyk, Rafal; Park, Il Woong; Dorao, Carlos Alberto (Journal article; Peer reviewed, 2019)The paper presents an experimental investigation of a silicone based heat exchanger, with passive heat transfer intensification by means of surface enhancement. The main objective of this paper was to experimentally ... -
Investigations on mixture preparation for two phase adiabatic pressure drop of R134a flowing in 5 mm diameter channel
Muszynski, Tomasz; Andrzejczyk, Rafal; Dorao, Carlos Alberto (Journal article; Peer reviewed, 2017)The article presents detailed two-phase adiabatic pressure drops data for refrigerant R134a. Study cases have been set for a mass flux varying from 200 to 400 kg/m2 s, at the saturation temperature of 19.4 ◦C. Obtained ...
