High velocity horizontal gas jets are applied to various industrial processes. In this work, a new thermal technique has been developed to measure the penetration length of horizontal gas jets. Experiments were conducted in a fluidized bed with a height of 1.23m and a rectangular cross section of 0.10m × 0.50m. The fluidized bed particles, which were either petroleum coke or sand, were heated by an in-bed electrical heater to temperatures between 300°C and 500°C. Cold gases, such as helium, nitrogen, carbon dioxide, were injected into the hot fluidized bed via a horizontal nozzle operating over a range of velocities. Based on the experimental results, a new empirical correlation was developed to predict the penetration length of jets issuing from the horizontal sonic nozzle at high temperature.
