    Liquid Level Sensor in Automotive Design
    (Iaria Xps Press, 2011) Erdem, Mehmet Emre; Gunes, Dogan
    New materials and technological developments in electronics and computers have changed all of the industries, as well as the world itself. These technological advancements have evolved automotive industry by redefining the concepts like: performance, efficiency, fuel consumption, driving dynamics, ergonomics etc. to a level far beyond expected. In this paper, the development stages; including the finite element analysis of the current sensors, using finite element analysis to design a new sensor, is elaborated. The new model designed in this study is computationally validated for production purposes and is planned to be experimentally tested. Also, in this paper a novel liquid level sensing device development strategy is presented in detail.

    The Derivation of System Parameters for a Ground Source Heat Pump (GSHP)
    (Int Journal Renewable Energy Research, 2025) Camdali, Unal; Tunc, Murat; Erdem, Mehmet Emre; Tuncel, Erhan
    well known the widespread use of nonrenewable energy sources such as fossil fuels cause environmental problems. Ground source heat pumps (GSHP) are highly efficient renewable energy system used for heating and cooling where cool deep ground source is used for higher efficiency. In this study, a new simulation model has been developed and used for heat pumps for low global warming potential (GWP) refrigerants such as R134a and validated by the experimental data. Also, the system parameters of a GSHP are obtained theoretically for heating and cooling modes of a building, located in Bolu City, Turkey. For this purpose, non-linear equations are determined by considering GSHP models in relevant literatures for heating and cooling capacity of 1.4 and 2.2 kW respectively for a building having dimensions as 4.4 m x 2.2 m x 3.6 m. In this respect, COPs for heating and cooling are calculated and obtained results are depicted. An algorithm is generated to design the R134a refrigerant heat exchanger to maximize the efficiency.
