In the present investigation, a numerical study has been done to analyse the effect of attachment of brokenV-shaped ribs on the heating surface of the triangular-shaped solar air heater duct. The roughness andflow parameters include relative roughness pitch (between 8 and 14), angle of attack (between 30 and 75degrees) and Reynolds number (between 4000 and 20,000). The effect on heat transfer and flow characteristicshas been observed due to variation in parameters. Considerable enhancement in convective heattransfer is observed along with frictional effect and indicated by Nusselt number and friction factor values.All the variations resulted in an increase in the performance of a solar air heater, which was indicated bythe value of the thermohydraulic performance parameter being more than 1.
