Coupling structure of multi-field primordial perturbations [PDF]

Journal of Cosmology and Astroparticle Physics, 2013
We investigate the coupling relations among perturbations in general multi-field models. We derived the equations of motion for both background and perturbations in a general basis. Within this formalism, we revisit the construction of kinematic orthogonal normal vectors using the successive time derivatives of the background field velocity.

A multi-field coupling simulation model for the centrifugal pump system

Mechanics & Industry, 2023
In this paper, a multi-field coupling simulation model, including the motor, shaft, and pump, is established to analyze the motor's influence and the shaft on the pump's operating status. First of all, different forms of simulation calculation models are established according to each device's characteristics.
