We present an effective finite element method (FEM) for the multiterm time-space Riesz fractional advection-diffusion equations (MT-TS-RFADEs). We obtain the weak formulation of MT-TS-RFADEs and prove the existence and uniqueness of weak solution by the Lax-Milgram theorem. For multiterm time discretization, we use the Diethelm fractional backward finite difference method based on quadrature. For spatial discretization, we show the details of an FEM for such MT-TS-RFADEs. Then, stability and convergence of such numerical method are proved, and some numerical examples are given to match well with the main conclusions.

The bronchial airways are an important part of the respiratory system, it is not uncommon for the bronchi to experience disturbances, one of the disorders due to coronavirus diseases (Covid-19). Coronavirus diseases (Covid-19) are what cause narrowing of the bronchial tubes so that they will interfere with the speed of air flow. This airflow speed will be modeled with mathematical language. The mathematical model of air flow velocity in this study is formed based on equations of momentum equations which are then solved by the finite element method. Speed ​​analysis Air flow was simulated using MATLAB and FLUENT software. The problems studied are the effect of the narrowing diameter, initial velocity, and viscosity on the air flow velocity. Based on the research results show that the smaller the narrowing diameter and the viscosity of the incoming air, the greater the airflow velocity, while for the greater the initial velocity, the greater the resulting airflow velocity.
