The Time Bubble


Book Description

Charlie and Josh's interests were the same as most other teenagers: drinking, parties and girls. That was until the day they discovered the Time Bubble. It starts at a bit of fun, jumping a few seconds into the future. Soon things take a more serious turn as the leaps in time increase in duration. When a teenage girl goes missing, and the police become involved, suspicion falls on Charlie. How can he explain where she is? Will anyone believe him? As the long term dangers of the Bubble become clear, one man comes up with a solution - one that could hold the key to his own salvation. Set in a small market town in Southern England in the early 21st century, this light-hearted time travel novel has plenty to delight readers of all ages. This novel is the first part of a trilogy. Global Cooling, the second in the series, is now available.




Global Cooling


Book Description

Ten years have passed since Charlie and Josh discovered The Time Bubble. As they wait for Peter to emerge after several years inside, Earth is facing a global climate catastrophe. An asteroid strike blankets the globe in dust and ash, blocking out the sun. Soon temperatures begin to fall. As weather conditions worsen, the members of The Time Bubble team need to make a decision - flee south to escape the weather, or wait for the worst to pass. Choosing to stay, D.I. Hannah Benson soon has more to worry about than keeping law and order. With power supplies failing and food scarce, it soon becomes a battle just to stay alive. And there are some that see it not as a crisis, but as an opportunity. Meanwhile, Josh sets out to investigate the possible existence of a new Time Bubble in Cornwall. With girlfriend Alice along for the ride, their travel plans are soon disrupted by the deepening winter. Can they reach the Bubble and use it to escape? Set a decade after the main events of The Time Bubble, this sequel takes place in parallel with events in the latter stages of that story.




The Bubble Book


Book Description

The Bubble Book was written to introduce and excite my preschool classroom about Belly Breaths through a fun, interactive experience. We use these Belly Breaths as a tool to get our bodies calm and settled after a rough moment on the playground, before nap time, or just to get feeling good again. Belly Breaths are an important first step towards emotion regulation and mindfulness. They bring more oxygen to the brain so we can process what is happening and think more clearly. I use this book to simply introduce the term "Belly Breaths" to my kiddos in a fun and engaging activity. Then, when the time comes, I can say, "Remember the Belly Breaths? Let's give them a try!"







The Acoustic Bubble


Book Description

The Acoustic Bubble describes the interaction of acoustic fields with bubbles in liquid. The book consists of five chapters. Chapter 1 provides a basic introduction to acoustics, including some of the more esoteric phenomena that can be seen when high-frequency high-intensity underwater sound is employed. Chapter 2 discusses the nucleation of cavitation and basic fluid dynamics, while Chapter 3 draws together the acoustics and bubble dynamics to discuss the free oscillation of a bubble and acoustic emissions from such activity. The acoustic probes that are often applied to study the behavior of a bubble when an externally-applied acoustic field drives it into oscillation is deliberated in Chapter 4. The last chapter outlines a variety of effects associated with acoustically-induced bubble activity. The bubble detection, sonoluminescence, sonochemistry, and pulse enhancement are also covered. This publication is a good reference for physics and engineering students and researchers intending to acquire knowledge of the acoustic interactions of acoustic fields with bubbles.




Bubble Systems


Book Description

This monograph presents a systematic analysis of bubble system mathematics, using the mechanics of two-phase systems in non-equilibrium as the scope of analysis. The author introduces the thermodynamic foundations of bubble systems, ranging from the fundamental starting points to current research challenges. This book addresses a range of topics, including description methods of multi-phase systems, boundary and initial conditions as well as coupling requirements at the phase boundary. Moreover, it presents a detailed study of the basic problems of bubble dynamics in a liquid mass: growth (dynamically and thermally controlled), collapse, bubble pulsations, bubble rise and breakup. Special emphasis is placed on bubble dynamics in turbulent flows. The analysis results are used to write integral equations governing the rate of vapor generation (condensation) in non-equilibrium flows, thus creating a basis for solving a number of practical problems. This book is the first to present a comprehensive theory of boiling shock with applications to problems of critical discharge and flashing under the fast decompression conditions. Reynolds’ analogy was the key to solving a number of problems in subcooled forced-flow boiling, the theoretical results of which led to easy-to-use design formulas. This book is primarily aimed at graduate and post-graduate students specializing in hydrodynamics or heat and mass transfer, as well as research expert focused on two-phase flow. It will also serve as a comprehensive reference book for designers working in the field of power and aerospace technology.




Cavitation and Bubble Dynamics


Book Description

Cavitation and Bubble Dynamics deals with fundamental physical processes of bubble dynamics and cavitation for graduate students and researchers.




Hydrodynamics and Mass Transfer in Downflow Slurry Bubble Columns


Book Description

Slurry bubble column reactors are intensively used as a multiphase reactor in the chemical, biochemical, and petrochemical industries for carrying out reactions and mass transfer operations in which a gas, made up of one or several reactive components, comes into contact or reacts with a liquid. This volume describes the hydrodynamics of three-phase gas-liquid-solid flow in a downflow slurry bubble column. The efficiency of the downflow gas interacting system is characterized by the self-entrainment of secondary gas. The book covers the gas entrainment phenomena, gas holdup characteristics, pressure drop, gasliquid mixing characteristics, bubble size distribution, interfacial phenomena, and the mass transfer phenomena in the downflow slurry system. This volume will be useful in chemical and biochemical industries and in industrial research and development sectors, as well as in advanced education courses in this area. The book will be helpful for further understanding the multiphase behavior in gas interacting multiphase systems for research and development. The hydrodynamic and mass transfer characteristics discussed will be useful in the design and installation of the modified slurry bubble column in industry for specific applications.
