PROBLEM: IVD-39BOOK: ENGINEERING THERMOFLUIDS, M. MASSOUD 39. Show that the steady state temperature distribution in a cylindrical spine is thesolution to:d²e(x) _ (m? + m? p(x) = 0dx2where m. = (Ph JkA)0³, and m, = (Ph,/kA)05. Use the given data to find the tem-perature distribution at steady state in the above fin. Data: L= 15 cm, D = 1 cm,TB = 350 C, T; = 27 C, k = 50 W/m-C, h. = 15 W/m².C, ɛ= 0.75. The tip of the finis losing energy by both radiation and convection.[Hint: You may solve this problem analytically or numerically. The analyticalsolution follows the method described in Section 8 of Chapter IVa. Since we havelinearized the differential equation by choosing the heat transfer coefficient, asshown in Problem 38, an iterative solution is required regardless of the solutionmethod we choose (h,, therefore, m, are unknowns). The initial guess to estimateh, for thermal radiation is obtained by ignoring thermal radiation (i.e., by settingm, = 0). Upon obtaining the initial guess for temperature, we then include thermalradiation but evaluate h, at the temperature calculated in the previous iteration. Atthe end of each trial, we find:%D%DTk - Tk-1E =where k is the iteration index. The iteration is terminated when ɛ <ɛ, where &, isthe specified convergence criterion].

ns are always required to be used only when the convective heat transfer coefficient h are…

please make it 1 paragraph in the abstract below, with the journal name Optimizing the thermal management system of PCM fin-structured Li-ion batteries under mechanical vibration conditions: A comparative study because I have difficulty combining can you please ask for help to try the writing below, so that the results are maximized The thermal management of battery systems using Phase Change Materials (PCM) commonly faces challenges due to the low thermal conductivity of PCM. This study introduces innovative fin structures comprising longitudinal fins and cylindrical rings to enhance heat transfer. Comparative experiments are initially designed to assess the thermal performance of various Battery Thermal Management Systems (BTMS). Results indicate that the PCM-Fin system outperforms both the pure battery system and the PCM system. Numerical simulations, validated with experimental data, uncover the underlying mechanisms. The fin structures not only increase the heat transfer area…
