Simulation and Analysis of Fluid Flow Around Thermowells Using MATLAB

Accurate analysis of fluid flow around thermowells is essential for designing reliable temperature measurement systems in process industries. In this study, MATLAB is employed to simulate flow around cylindrical thermowells with diameters of ۶ mm, ۱۲ mm, and ۲۰ mm and insertion lengths of ۵۰ mm, ۱۰۰ mm, and ۱۵۰ mm. Flow rates ranging from ۰.۰۱ to ۰.۱ m³/s are analyzed, and velocity, Reynolds number, and pressure drop (AP) are computed to visualize flow disturbances and wake formation. For clarity, AP vs Q and Re vs Q are presented as separate plots for each thermowell length, facilitating interpretation of trends. Results indicate that larger diameters and longer thermowells significantly increase local AP and wake size.
