Shell Side Fluid Velocity of Baffled HX & Re - Nobody knows last resort

Click For Summary
SUMMARY

The discussion focuses on calculating the shell side fluid velocity for a Shell and Tube Heat Exchanger (HX) with baffles, specifically addressing the challenges in determining the Reynolds number for this flow. Key parameters include mass flow on the shell side (ms), number of tubes (Nt), length of the tube bundle (Lt), number of baffles (Nb), inside diameter of the shell (Dis), and volumetric flow rate (Vs). The participant highlights the difficulty in finding applicable equations for the shell side, contrasting it with the simpler calculations for the tube side.

PREREQUISITES
  • Understanding of Shell and Tube Heat Exchanger design
  • Knowledge of fluid dynamics principles, including Reynolds number calculation
  • Familiarity with baffle configurations and their impact on flow
  • Proficiency in calculating mass flow and volumetric flow rates
NEXT STEPS
  • Research equations for calculating shell side fluid velocity in baffled heat exchangers
  • Study the impact of baffle spacing and configuration on flow dynamics
  • Learn about the significance of Reynolds number in determining flow regime
  • Explore resources such as "Heat Exchanger Design Handbook" for comprehensive design guidelines
USEFUL FOR

Design engineers, thermal engineers, and anyone involved in the design and analysis of heat exchangers, particularly those working with shell and tube configurations.

Shell Side Fluid Velocity of Baffled HX & Re -- Nobody knows last resort

Problem:
I need to know how to calculate the shell side fluid velocity for a Shell&Tube HX with *Baffles*. Also, the reynolds number for this flow

Known:
ms -Mass flow on shell side
Nt -Number of tubes
Lt -Length of tube bundle
Nb - Number of Baffles
Dis -Inside Diameter of Shell
Vs -Volumetric flow rate

--Also I know all fluid properties for shell side fluid i.e. Cp, rho, viscosity...

Comments: I have completed this for the tube side it was very simple but the shell side is difficult and can not find any equations to apply.

I will have to order the book I can't seem to figure it out. Thank you.
