Theoretical Results

Nonnegative matrix factorization numerical method has been used to improve the spectral resolution of integrated photonic cavity based spectroscopy. Based on the experimental results for integrated photonic cavity device on Optics Letters 32, 632 (2007), the theoretical results show that the spectral resolution can be improved more than 3 times from 5.5 nm to 1.8 nm. It is a promising way to release the difficulty of fabricating high-resolution devices.

Fundamental Equations

A numerical method for simulating gravitational flows in atmospheric conditions is presented. This is based on the preconditioning method, Roe’s Riemann solver, the 4th-order compact MUSCL extrapolation, and the LU-SGS scheme. The fundamental equations for governing condensate flows with homogeneous and heterogeneous nucleations are transformed to the preconditioned equations. Natural convections with and without condensation at 1g and 0g around a circular cylinder are numerically investigated.
