Abstract: This study investigates the heat transfer and fluid flow phenomena in a tubular reactor designed for biomass pyrolysis, using both experimental and numerical methods. A comprehensive 3D Computational Fluid Dynamics (CFD) model was developed in COMSOL Multiphysics, incorporating the reactor geometry, operating parameters, and biomass properties to simulate thermal behavior. Experiments were conducted with chicken wing bones as feedstock, with temperatures monitored at three points along the reactor to validate the model. The simulations replicated experimental conditions, including nitrogen flow at 0.5 l/min and reactor wall temperature set at 550 °C.
