In this paper, fluid flow and heat transfer in the laboratory (small size) shell tube heat exchanger are analysed by computational fluid dynamic software. In this type of shell tube heat exchanger baffles with different angles of rotation: 00 (horizontal segmental baffle), 150 (from horizontal), 300, 450, 600, 750, 900 (vertical segmental baffle) is used. Effect of baffle orientation on shell t...

Abstract The article deals with the adjustment of flow rate milk and water by a plate heat exchanger, which is used for precooling milk. First, measurements parameters device in stable were carried out. Subsequently, exchanger was measured laboratory. Water at 35 °C instead Different ratios cooling cooled (instead milk) set. From values, changes temperature calculated depending on its constant ...

The paper presents the results of a study frost formation on surface heat exchanger fins when moist air flow is flown around. description experimental stand and procedure are given. effect efficiency transfer was estimated from time temperature dependences at various points fin surface. During experiments, thickness layer degree overlap intercostal spaces were monitored visually using an anemom...

This paper presents a comprehensive and exclusive thermodynamic analysis of counter flow heat exchanger under various operating and geometrical conditions. Analysis system (ANSYS) workbench 14.0 has been used for computational analysis and comparison with previous literature has been carried out in view of variable temperature and mass flow rate of hot and cold fluids. An analytical and statist...
