摘要：

The main objective of this work is to propose a new hydrogen leakage visualization method to evaluate hydrogen jet pressure. A mathematical model is proposed to reveal the intensity distribution of the laser beam through the hydrogen jet at different outlet pressures. Our findings show that the hydrogen jet can be regarded as a gas lens with adjustable laser beam energy, and a change in jet pressure causes a change in the halfheight width of the spectrum, which affects the intensity distribution of the laser beam after it passes through the hydrogen jet. The error between the light intensity distribution of the theory and the light intensity distribution obtained from the experimental results is 2.59%. The error is within the allowable range. Our technique shows that the variation of the hydrogen jet pressure can be estimated by analyzing the intensity data after the laser passes through the hydrogen jet.(c) 2023 Hydrogen Energy Publications LLC.
