本文是以數值研究詳細地探討當流體流過上下皆為加熱V型波狀板壁面的渠道時所產生的流場及其熱傳特性。在數值計算的方法上，以控制體積法為基礎，配合有限差分法及冪次法則在非結構三角型網格上將各統御方程式離散成差分方程式，並且運用SIMPLE法來求解動量方程式中的壓力項與速度項結合問題。對於紊流運動行為及結構問題是以k-ε雙方程紊流模式來描述。
本文所研究的參數有：雷諾數(2000~5500)、V型波板壁面角度(θ=20度、40度、60度)、等熱通量(580W/m^2、830W/m^2、1090W/m^2)。
數值研究結果與Naphon(2007)的實驗數據經驗證相當吻合。V型波板壁面壁面角度(θ)及雷諾數對於渠道內的流場、溫度分佈、熱傳率皆有顯著的影響。當V型波板壁面壁面角度增加時，會使得壁面熱量較容易傳至中央流場，提高整體溫度及熱傳效率，但也提高流體流過渠道時的壓降；雷諾數增加會使得流體擾動更複雜，也會提高其熱傳效率。另外，以採用非平衡牆函數的數值計算在對高雷諾數或複雜流場的問題時，會比採用標準牆函數的結果有較高的準確度。

The detailed numerical study is carried out to investigate fluid flow and heat transfer characteristics in channel with heated V corrugated upper and lower plates. The governing equations are discredited by a Control-Volume-Based finite-difference method with power-law scheme on unstructured triangular grid, the coupling of velocity and the pressure terms of momentum equations are solved by SIMPLE (Semi-Implicit Method for Pressure-Linked Equation) algorithm. And the well-known turbulence model is employed to describe the turbulent structure and behavior.
The parameters studied include Reynolds number (Re=2000~5500), angles of V corrugated plates (θ=20o、40o、60o), constant heat flux ( =580W/m2、830W/m2、1090W/m2).
The numerical results have been validated using the experimented data reported by Naphon(2007),and the good agreement has been found. The angles of V corrugated plates (θ) and the Reynolds number are demonstrated to significantly affect the fluid flow, temperature distribution, and heat transfer rate. Increasing the angles of V corrugated plates can make the wall heat transfers to the central flow easier, the whole temperature increases, the heat transfer performance becomes better, and higher pressure drop. Reynolds number increasing leads to the fluid flow more complex and heat transfer rate. In addition, the numerical calculations with non-equilibrium wall function have a better accuracy than with standard wall function for solving the high Reynolds number or complex flow problems.
