This paper investigates the impact of bulk viscosity within framework f(T,B) gravity. We consider a time-dependent model with particular Hubble parameter expression. Here, we looked into viability well-motivated gravity model, which takes form f=αlog(B)+βT, and has free parameters α β. The 46 observational data (OHD) in range 0≤z≤2.36 were used to constrain achieve solution. have Markov Chain M...
