"This book presents new methods of numerical modelling of tube heat exchangers, which can be used to perform design and operation calculations of exchangers characterized by a complex flow system. It also proposes new heat transfer correlations for laminar, transition and turbulent flows. A large part of the book is devoted to experimental testing of heat exchangers, and methods for assessing the indirect measurement uncertainty are presented. Further, it describes a new method for parallel determination of the Nusselt number correlations on both sides of the tube walls based on the nonlinear least squares method and presents the application of computational fluid dynamic (CFD) modeling to determine the air-side Nusselt number correlations. Lastly, it develops a control system based on the mathematical model of the car radiator and compares this with the digital proportional-integral-derivative (PID) controller. The book is intended for students, academics and researchers, as well as for designers and manufacturers of heat exchangers."

"Dalam penelitian ini dilakukan study tentang pengaruh ion chlorida terhadap pemanfaat inhibitor nitrit dan betz didalam air pendingin. Dari penelitian tersebut diketahui bahwa :1. Pemakaian inhibitor nitrit, efektif untuk air baku tanpa NaCl dan yang mengandung NaCl 20,200 & 400 ppm setelah konsentrasi inhibitor masing-masing melebihi 150 ppm, 200 ppm, 300 ppm dan 500 ppm.2. Pemakaian inhibitor betz, efektif untuk air baku tanpa NaCl dan yang mengandung NaCl 20,200 & 400 ppm setelah konsentrasi inhibitor masing-masing melebihi 100 ppm, 150 ppm, 400 ppm dan 600 ppm.3. Pada konsentrasi NaCl yang rendah pemakaian inhibitor Betz lebih efektif dibanding inhibitor nitrit.4. Sedangkan pada konsentrasi NaCl yang tinggi pemakaian inhibitor nitrit lebih efektif dibanding inhibitor betz."
