Abstract A modified gas kinetic Bhatnagar-Gross-Krook (BGK) scheme for microflow has been developed upon the simultaneous collision model. Based on experimental and numerical results, the sub-choked pressure ratios are investigated. The current numerical approach is validated to provide a practical solution for microchannel flow.
