AV (area velocity) value

Definition(s)

AV (area velocity) value

"AV (area velocity) value" means a value of the exhaust gas flow rate passing through the catalyst blocks (m3/h) per total active surface area of the catalyst blocks in the SCR chamber (m2). Therefore, unit of AV value is (m/h). The exhaust gas flow volume is the volume defined at 0°C and 101.3 kPa.
