Understanding Shell and Tube Heat Exchangers
Shell and tube heat exchangers represent the most common class of shell and tube design used in oil refineries and large chemical processes. They are suited for higher-pressure applications. This tool provides robust mathematical estimations based on core thermodynamic principles, energy balance, and heat transfer equations. Proper design ensures optimal thermal recovery, minimal fluid friction losses, and extended structural integrity across industrial deployment cycles.
Formulas Used
- Heat Duty ($Q$): $Q = \dot{m} C_p \Delta T$
- Log Mean Temperature Difference ($LMTD$): Calculated using counter-current temperature differences $\Delta T_1$ and $\Delta T_2$.
- Heat Transfer Surface Area ($A$): $A = \pi \times d_o \times L \times N_{tubes}$
How to Use This Calculator
Input the precise mass flow rates, specific heat capacities, and fluid temperatures for both the shell side and the tube side into their respective designated columns. Next, specify the physical geometry parameters such as tube inner/outer diameter, active length, total tube count, and expected overall heat transfer coefficient.
