Phase Change Materials (PCM) is one of the heat storage devices and it is a key technology for waste heat recovery. PCM possess a great capacity of accumulation of energy in their temperature of phase transition between liquid and solid. Thus, it is of substantial importance to understand the thermal transport property of the PCM in both solid and liquid state. In spite of that, there are few reports about the thermal conductivity of the PCM in liquid state. This work evaluates the thermal conductivity and the electrical resistivity of the liquid Sn-Bi alloy which is one of the PCM.
July 31, 2017 Due to the end of the Yahoo!JAPAN OpenID service, My J-STAGE will end the support of the following sign-in services with OpenID on August 26, 2017: -Sign-in with Yahoo!JAPAN ID -Sign-in with livedoor ID * After that, please sign-in with My J-STAGE ID.
July 03, 2017 There had been a service stop from Jul 2‚ 2017‚ 8:06 to Jul 2‚ 2017‚ 19:12(JST) (Jul 1‚ 2017‚ 23:06 to Jul 2‚ 2017‚ 10:12(UTC)) . The service has been back to normal.We apologize for any inconvenience this may cause you.
May 18, 2016 We have released “J-STAGE BETA site”.
