Understanding the deposition phenomena is important because it is encountered in numerous areas of engineering which includes thin film wafer production in semiconductor, surface finishing coatings and fouling in heat exchangers and piping. Experimental investigation is challenging because of numerous factors, for example in certain cases the time scales could be very long or it may involve extreme and hazardous environments. Expensive high resolution equipment is needed for experiments involving thin film production. Numerical simulations are a complimentary way of studying these phenomena. This study presents a fixed mesh approach to model the convective-diffusive particle deposition on surfaces. Validations are made against solutions of the total concentration approach for one- and two-dimensional depositions with and without convective effect. The presented approach is then employed to investigate deposition on single- and multi-tube arrays in a cross-flow configuration.
