Modelling linered engine blocks

Factors that affect heat transfer in the linered aluminium engine block are examined to determine their importance. Conduction is found to be the dominant mode of heat transfer, and the interface is characterised as imperfect contact if there are no surface manufacturing defects larger than 139 microns. A model is proposed to estimate the effective conductivity for imperfect contact. This thermal conductance depends on the area of contact, macroscopic roughness, the contact pressure and the interstitial medium. The transfer of heat and the distribution of stress in line red engine blocks are coupled, and the problem is strongly non-linear. A finite element solution procedure for solving the heat transfer problem in the linered engine block is outlined

Person to Person in Japan

While still in the midst of their study abroad experiences, students at Linfield College write reflective essays. Their essays address issues of cultural similarity and difference, compare lifestyles, mores, norms, and habits between their host countries and home, and examine changes in perceptions about their host countries and the United States. In this essay, Van Ha describes his observations during his study abroad program at Rikkyo University in Tokyo, Japan

Ha Baode on his family history

This interview with Ha Baode was recorded in the summer of 2009. A transcription is attached. This interview focuses on the migration of Ha Baode’s family from the clan’s home place in Huzhu, Qinghai, to Hawan in Gansu.Researchers Ha Mingzong (Sangji Zhaxi) and Ha Mingzhu (Taimei) interviewed Mongghul Ha Clan elders about clan history and digitally documented (video taped; audio-recorded) the interviews.World Oral Literature Projec
