Abstract:

A temperature control system and method for use with an exhaust flow simulation system. A typical exhaust flow simulator is a burner-based system, in which exhaust from a combustive burner is exhausted through an exhaust line. A temperature control section divides the exhaust from the burner line into two paths: a cool path and an uncooled (hot) path. The cool path uses a heat exchanger to cool the exhaust. The cool path also has a control valve that controls the relative portions of hot and cool exhaust, which are re-mixed downstream the valve into an exhaust line. Various embodiments have different configurations for the two paths.
