Experimental investigation of deposit formation using foils in hot air test bench. Increase of temperature and flow rate decreases the deposit formation. Time dependent deposit formation helps for SCR designers to predict deposit formation. Deposit film area, location and nature at different temperature and flow rate. Phenomenological modelling helps in choosing optimum SCR design.
