Abstract:Classical transport based on simple particle collisions theory underestimates the rates of energy losses. The main sources of energy transport are instabilities due to fluctuations in magnetic fields, electric fields, and plasma density and/or temperature gradient. Although many theoretical models have been introduced to describe anomalous transport mechanisms, none of the proposed models, alone, provides a satisfying description of the experimental data. In recent years, there has been a great interest in the theoretical multiple mode tokamak transport model. In this study, we develop methods for testing models which contain a linear combination of several theoretical transport fluxes, namely, drift waves, resistive ballooning, and rippling modes added to a fixed level of neoclassical transport. The purpose of this work is to calibrate the proposed model against existing L-mode energy confinement time data.
