This paper focuses on obtaining the exact solutions to the variable-coefficient forced Korteweg-de Vries (KdV) equation for modeling spatial inhomogeneity in fluids. By combining the direct similarity reduction-based CK method with the $(G'/G)$ expansion method, three new similarity solutions are obtained for this variable-coefficient forced KdV equation.
