Purpose: Numerical investigation of mixed convection processes to assess the feasibility of using jet heaters for local heating in locomotive depot welding stations with a mechanical localized ventilation system. Methods: The research has been conducted using the finite difference method in the COMSOL Multiphysics software, with the problem of mixed convection formulated and the calculation domain reduced to a two-dimensional plane. Results: Temperature fields and velocity maps have been obtained for the workstations under various conditions and positions of the jet heater. The analysis of the results has allowed us to propose options for using jet heaters and their installation locations, as well as to refine the impact of their impact on the microclimate of the workstation. The conditions under which the use of jet heaters is both practical and safe have been determined. Practical significance: The results obtained during the study can be used for the organization or optimization of local heating systems for welding stations in locomotive depots, as well as for similar workplace arrangements.
