Abstract : Two Component Advective Flow (TCAF) contains thermal radiation dominated Keplerian disk and Comptonization dominated CENtrifugal pressure supported BOundary Layer (CENBOL) produced by an advective halo through shock transition. We model the CENBOL as a thick disk having natural angular distribution around a black hole. CENBOL acts as the electron cloud. Gravitational bending of photons is implemented. Time evolution of photons have been calculated separately for Comptonization, disk reflection and gravitational bending. Images of TCAF is presented for various inclination angles. Cumulative time lag effects have been plotted against the inclination angle. Parameters, like, CENBOL size, accretion rate are varied. From these simulations we obtain an idea of how the time lag properties should behave as a function of energy, inclination angle, and the flow parameters.
