Flow Through Helical Coil
Helical coils are used for heating or
cooling in process tanks. When a fluid flow through a curved tube,
centrifugal force acting upon the various elements of fluid moving with
different velocities causes secondary circulation. Secondary flow
results in higher heat transfer characteristics. Further secondary flow
stabilizes the laminar flow leading of a higher critical Reynolds number
for transition from laminar to turbulent flow.
- To determine the critical Reynolds number of a fluid flowing through the coil.
- To determine the friction factor for flow of water through helical coil
- To compare the pressure drop in helical coil with that in a straight pipe of same length, inside diameter and surface roughness
- Electricity 500 watts, 220 V, 1 phase
