Simulation of stirred yoghurt processing in plate heat exchangers
In the present work, simulations of stirred yoghurt processing in a plate heat exchanger were performed using computational fluid dynamics (CFD) calculations and the results compared with experimental data, showing a very good agreement. A Herschel–Bulkley model for the viscosity and an Arrhenius-type term for the temperature dependence were used to model the thermo-rheological behaviour of yog...
متن کاملHeat transfer and rheology of stirred yoghurt during cooling in plate heat exchangers
In the present work an experimental investigation was conducted to obtain a correlation for the determination of convective heat transfer coefficients of stirred yoghurt in a plate heat exchanger. A rheological study was carried out in order to characterise the stirred yoghurt flow behaviour, evaluating its dependency both on shear rate and temperature. A shift in the temperature dependency was...
متن کاملThermal behaviour of stirred yoghurt during cooling in plate heat exchangers
In this study, CFD calculations were made in order to analyse the thermal behaviour of yoghurt in a plate heat exchanger, the yoghurt viscosity being described by a Herschel–Bulkley model. The influence of Reynolds number on local Nusselt numbers was analysed as well as the influence of entry effects on average Nusselt number. Numerical runs considering and discarding the influence of temperatu...
متن کاملEffectiveness of parallel-plate heat exchangers in thermoacoustic devices
Measurements are made of the heat transferred between two identical parallel-plate heat exchangers under conditions of oscillating flow over a range of frequencies and amplitudes. The results are analyzed and summarized in terms of heat-exchanger effectiveness, the ratio of the actual heat transfer rate to the maximum possible heat transfer rate. Measured results are compared to the DELTAE mode...
متن کاملExperimental Heat Transfer Studies of Water in Corrugated Plate Heat Exchangers: Effect of Corrugation Angle
In the present investigations heat transfer studies are made in three different types of corrugated plate heat exchangers having a length of 30 cm and width of 10 cm. The corrugated channel has a spacing of 5 mm. Three different corrugation angles are used in this study which are 30 0 , 40 0 and 50 0 . Water is taken as test fluid as well as the heating medium. The wall temperatures are measure...
