Method for generating porous material microstructure with set effective thermal conductivity and related device

The invention belongs to the field of porous materials, and discloses a porous material microstructure generation method with set effective thermal conductivity and a related device, and the method comprises the following steps: obtaining a random noise image and setting the effective thermal conductivity; according to the random noise image and the set effective thermal conductivity, a porous material microstructure image with the set effective thermal conductivity is generated through a pre-trained improved condition diffusion model; wherein the improved conditional diffusion model is obtained by modifying a denoising neural network in the conditional diffusion model into a denoising neural network with a double up-sampling channel decoder. According to the improved conditional diffusion model, the denoising neural network with the double-up-sampling-channel decoder is adopted, so that the denoising neural network has flexible coding depth and can better adapt to generation of the microstructure of the poro
