The NTU (Nuzzle-Thermal-Unger method) is a widely used numerical approach for analyzing the heat transfer between two parallel plates maintained at different temperatures. This method employs a computational grid that encloses the entire geometry, with each element representing a small portion of the boundary layer.
The NTU method solves the heat transfer equation in a two-dimensional, laminar flow regime, assuming constant thermal conductivity and negligible mass transfer. By dividing the entire domain into grid cells, the NTU method effectively reduces the dimensionality of the problem and simplifies the solution process.
The NTU method uses a finite difference approximation to solve the heat transfer equation at each point in the computational grid. The solution provides the temperature distribution in the region between the two plates, including temperature values, temperatures at the boundaries, and heat flux distribution.
Compared to other numerical methods, the NTU method possesses several advantages. It is computationally efficient, requiring only a few grid points to represent the entire domain, resulting in reduced computational time and memory consumption. Additionally, it provides accurate results for various flow regimes, including laminar and turbulent flows
