Abstract

The invention discloses a flue gas three-dimensional multi-physical field instantaneous measurement device and method, and the device comprises a visual diffusion box, a first platform, a second platform, and a schlieren measurement system composed of a schlieren background plate and a high-speed CCD camera. The TDLAS diode measurement system consists of a signal generator, a tunable laser, a first optical fiber coupler, a concentration signal generator, a temperature signal generator, a concentration signal sensor and a temperature signal sensor, the PIV measurement system consists of a PIV light source and a PIV special high-speed camera; according to the invention, the influence on the environment is small, the form change, the temperature field, the concentration field and the velocity field of the gas jet in the diffusion process can be accurately measured, and technical conditions can be created for establishing a smoke cloud diffusion model.

Description

technical field [0001] The invention belongs to the technical field of gas jet verification experiment research, and in particular relates to a flue gas three-dimensional multi-physical field instantaneous measurement device and method. Background technique [0002] Study the characteristics of smoke cloud diffusion and establish a smoke cloud diffusion model that can be used to invert the type of unknown explosion accident, equivalent or speculate on the model, power and damage effect of battlefield weapons, realize real-time and rapid detection of unknown explosion sources, remote evaluation of battlefield explosions, and off-site detection of explosion accidents Detection, rapid warning and assessment of detonation pollution by harmful substances are also of great value. [0003] Aiming at the problem of cloud diffusion, domestic and foreign academic circles have carried out a large number of related experiments for a long time. The external field test has a great impact...
