THANKS.
1. You have been asked to evaluate the effect of several factors on operation of thermal energy storage solutions. W Factors to be studied are storage tank design, storage materials and working fluid, as shown in Table Q3a. Following Taguchi methodology factors levels were selected, and each experiment was repeated three times. Measured performance (storage efficiency as %) is shown in Table Q3b. a (a) Using observation method, what can you conclude? [4 marks] (b) Using SN (signal-to-noise) methodology, determine the dominant factor. [11 marks] (c) Confirm the optimal combination of the operational parameters using main effect analysis. [8 marks] (d) Using graphical method show if there is any interaction between factors B and C.
